1225-1621 7.80e-110

Dock Homology Region 2, a GEF domain, of Dedicator of Cytokinesis proteins; DOCK proteins comprise a family of atypical guanine nucleotide exchange factors (GEFs) that lack the conventional Dbl homology (DH) domain. As GEFs, they activate the small GTPases Rac and Cdc42 by exchanging bound GDP for free GTP. They are also called the CZH (CED-5, Dock180, and MBC-zizimin homology) family, after the first family members identified. Dock180 was first isolated as a binding partner for the adaptor protein Crk. The Caenorhabditis elegans protein, Ced-5, is essential for cell migration and phagocytosis, while the Drosophila ortholog, Myoblast city (MBC), is necessary for myoblast fusion and dorsal closure. DOCKs are divided into four classes (A-D) based on sequence similarity and domain architecture: class A includes Dock1 (or Dock180), 2 and 5; class B includes Dock3 and 4; class C includes Dock6, 7, and 8; and class D includes Dock9, 10 and 11. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1, and DHR-2 (also called CZH2 or Docker). This alignment model represents the DHR-2 domain of DOCK proteins, which contains the catalytic GEF activity for Rac and/or Cdc42.

415-608 2.83e-42

C2 domains found in Dedicator Of CytoKinesis 1 (DOCK 180) and related proteins; Dock180 was first identified as an 180kd proto-oncogene product c-Crk-interacting protein involved in actin cytoskeletal changes. It is now known that it has Rac-specific GEF activity, but lacks the conventional Dbl homology (DH) domain. There are 10 additional related proteins that can be divided into four classes based on sequence similarity and domain organization: Dock-A which includes Dock180/Dock1, Dock2, and Dock5; Dock-B which includes Dock3/MOCA (modifier of cell adhesion) and Dock4; Dock-C which includes Dock6/Zir1, Dock7/Zir2, and Dock8/Zir3; and Dock-D, which includes Dock9/Zizimin1, Dock10/Zizimin3, and Dock11/Zizimin2/ACG (activated Cdc42-associated GEF). Most of members of classes Dock-A and Dock-B are the GEFs specific for Rac. Those of Dock-D are Cdc42-specific GEFs while those of Dock-C are the GEFs for both. All Dock180-related proteins have two common homology domains: the C2 domain (AKA Dock homology region (DHR)-1, CED-5, Dock180, MBC-zizimin homology (CZH) 1) and the DHR-2 (AKA CZH2, or Docker). DHR-2 has the catalytic activity for Rac and/or Cdc42, but is structurally unrelated to the DH domain. The C2/DHR-1 domains of Dock180 and Dock4 have been shown to bind phosphatidylinositol-3, 4, 5-triphosphate (PtdIns(3,4,5)P3). The C2 domain was first identified in PKC. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions.

DHR-2, Lobe A; This entry represents a conserved region within a number of eukaryotic dedicator of cytokinesis proteins (DOCK), which are guanine nucleotide exchange factors (GEFs), that activate some small GTPases by exchanging bound GDP for free GTP such as Rac. These proteins have a DOCK-homology region 1 (DHR-1, also known as DOCK-type C2 domain) at the N-terminus and a DHR-2 (also known as DOCKER domain) at the C-terminal. The DHR-2 is a GEF catalytic domain organized into three lobes, A, B and C, with the Rho-family binding site and catalytic centre generated entirely from lobes B and C. This entry represents Lobe A, formed from an antiparallel array of alpha helices that adopts a tetratricopeptide repeat-like fold, which through extensive contacts with lobe B, stabilizes DHR-2 domain.

8-67 2.84e-04

Src Homology 3 domain of Class A and B Dedicator of Cytokinesis proteins; DOCK proteins are atypical guanine nucleotide exchange factors (GEFs) that lack the conventional Dbl homology (DH) domain. They are divided into four classes (A-D) based on sequence similarity and domain architecture: class A includes Dock1, 2 and 5; class B includes Dock3 and 4; class C includes Dock6, 7, and 8; and class D includes Dock9, 10 and 11. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate while DHR-2 contains the catalytic activity for Rac and/or Cdc42. This subfamily includes only Class A and B DOCKs, which also contain an SH3 domain at the N-terminal region and a PxxP motif at the C-terminus. Class A/B DOCKs are mostly specific GEFs for Rac, except Dock4 which activates the Ras family GTPase Rap1, probably indirectly through interaction with Rap regulatory proteins. The SH3 domain of class A/B DOCKs have been shown to bind Elmo, a scaffold protein that promotes GEF activity of DOCKs by releasing DHR-2 autoinhibition by the intramolecular SH3 domain. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

Dock Homology Region 2, a GEF domain, of Dedicator of Cytokinesis proteins; DOCK proteins comprise a family of atypical guanine nucleotide exchange factors (GEFs) that lack the conventional Dbl homology (DH) domain. As GEFs, they activate the small GTPases Rac and Cdc42 by exchanging bound GDP for free GTP. They are also called the CZH (CED-5, Dock180, and MBC-zizimin homology) family, after the first family members identified. Dock180 was first isolated as a binding partner for the adaptor protein Crk. The Caenorhabditis elegans protein, Ced-5, is essential for cell migration and phagocytosis, while the Drosophila ortholog, Myoblast city (MBC), is necessary for myoblast fusion and dorsal closure. DOCKs are divided into four classes (A-D) based on sequence similarity and domain architecture: class A includes Dock1 (or Dock180), 2 and 5; class B includes Dock3 and 4; class C includes Dock6, 7, and 8; and class D includes Dock9, 10 and 11. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1, and DHR-2 (also called CZH2 or Docker). This alignment model represents the DHR-2 domain of DOCK proteins, which contains the catalytic GEF activity for Rac and/or Cdc42.

As GEFs, they activate small GTPases by exchanging bound GDP for free GTP. They are divided into four classes (A-D) based on sequence similarity and domain architecture; class A includes Dock1, 2 and 5. Class A DOCKs are specific GEFs for Rac. Dock1 interacts with the scaffold protein Elmo and the resulting complex functions upstream of Rac in many biological events including phagocytosis of apoptotic cells, cell migration and invasion. Dock2 plays an important role in lymphocyte migration and activation, T-cell differentiation, neutrophil chemotaxis, and type I interferon induction. Dock5 functions upstream of Rac1 to regulate osteoclast function. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of class A DOCKs, which contains the catalytic GEF activity for Rac and/or Cdc42.

Dock Homology Region 2, a GEF domain, of Class A Dedicator of Cytokinesis 1; Dock1, also called Dock180, is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates small GTPases by exchanging bound GDP for free GTP. Dock1 interacts with the scaffold protein Elmo and the resulting complex functions upstream of Rac in many biological events including phagocytosis of apoptotic cells, cell migration and invasion. In the nervous system, it mediates attractive responses to netrin-1 and thus, plays a role in axon outgrowth and pathfinding. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class A includes Dock1, 2 and 5. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of Dock1, which contains the catalytic GEF activity for Rac and/or Cdc42. Class A DOCKs, like Dock1, are specific GEFs for Rac and they contain an SH3 domain at the N-terminal region and a PxxP motif at the C-terminus.

Dock Homology Region 2, a GEF domain, of Class B Dedicator of Cytokinesis proteins; DOCK proteins are atypical guanine nucleotide exchange factors (GEFs) that lack the conventional Dbl homology (DH) domain. As GEFs, they activate small GTPases by exchanging bound GDP for free GTP. They are divided into four classes (A-D) based on sequence similarity and domain architecture; class B includes Dock3 and 4. Dock3 is a specific GEF for Rac and it regulates N-cadherin dependent cell-cell adhesion, cell polarity, and neuronal morphology. It promotes axonal growth by stimulating actin polymerization and microtubule assembly. Dock4 activates the Ras family GTPase Rap1, probably indirectly through interaction with Rap regulatory proteins. It plays a role in regulating dendritic growth and branching in hippocampal neurons, where it is highly expressed. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of class B DOCKs, which contains the catalytic GEF activity for Rac and/or Cdc42. Class B DOCKs also contain an SH3 domain at the N-terminal region and a PxxP motif at the C-terminus.

415-608 2.83e-42

C2 domains found in Dedicator Of CytoKinesis 1 (DOCK 180) and related proteins; Dock180 was first identified as an 180kd proto-oncogene product c-Crk-interacting protein involved in actin cytoskeletal changes. It is now known that it has Rac-specific GEF activity, but lacks the conventional Dbl homology (DH) domain. There are 10 additional related proteins that can be divided into four classes based on sequence similarity and domain organization: Dock-A which includes Dock180/Dock1, Dock2, and Dock5; Dock-B which includes Dock3/MOCA (modifier of cell adhesion) and Dock4; Dock-C which includes Dock6/Zir1, Dock7/Zir2, and Dock8/Zir3; and Dock-D, which includes Dock9/Zizimin1, Dock10/Zizimin3, and Dock11/Zizimin2/ACG (activated Cdc42-associated GEF). Most of members of classes Dock-A and Dock-B are the GEFs specific for Rac. Those of Dock-D are Cdc42-specific GEFs while those of Dock-C are the GEFs for both. All Dock180-related proteins have two common homology domains: the C2 domain (AKA Dock homology region (DHR)-1, CED-5, Dock180, MBC-zizimin homology (CZH) 1) and the DHR-2 (AKA CZH2, or Docker). DHR-2 has the catalytic activity for Rac and/or Cdc42, but is structurally unrelated to the DH domain. The C2/DHR-1 domains of Dock180 and Dock4 have been shown to bind phosphatidylinositol-3, 4, 5-triphosphate (PtdIns(3,4,5)P3). The C2 domain was first identified in PKC. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions.

C2 domain in Dock180 and Zizimin proteins; The Dock180/Dock1 and Zizimin proteins are atypical GTP/GDP exchange factors for the small GTPases Rac and Cdc42 and are implicated cell-migration and phagocytosis. Across all Dock180 proteins, two regions are conserved: C-terminus termed CZH2 or DHR2 (or the Dedicator of cytokinesis) whereas CZH1/DHR1 contain a new family of the C2 domain.

415-605 4.22e-39

C2 domains found in Dedicator Of CytoKinesis (Dock) class A proteins; Dock-A is one of 4 classes of Dock family proteins. The members here include: Dock180/Dock1, Dock2, and Dock5. Most of these members have been shown to be GEFs specific for Rac. Dock5 has not been well characterized to date, but most likely also is a GEF specific for Rac. In addition to the C2 domain (AKA Dock homology region (DHR)-1, CED-5, Dock180, MBC-zizimin homology (CZH) 1) and the DHR-2 (AKA CZH2, or Docker), which all Dock180-related proteins have, Dock-A members contain a proline-rich region and a SH3 domain upstream of the C2 domain. DHR-2 has the catalytic activity for Rac and/or Cdc42, but is structurally unrelated to the DH domain. The C2/DHR-1 domains of Dock180 and Dock4 have been shown to bind phosphatidylinositol-3, 4, 5-triphosphate (PtdIns(3,4,5)P3). The C2 domain was first identified in PKC. C2 domains fold into an 8-standed beta-sandwich that can adopt 2 structural arrangements: Type I and Type II, distinguished by a circular permutation involving their N- and C-terminal beta strands. Many C2 domains are Ca2+-dependent membrane-targeting modules that bind a wide variety of substances including bind phospholipids, inositol polyphosphates, and intracellular proteins. Most C2 domain proteins are either signal transduction enzymes that contain a single C2 domain, such as protein kinase C, or membrane trafficking proteins which contain at least two C2 domains, such as synaptotagmin 1. However, there are a few exceptions to this including RIM isoforms and some splice variants of piccolo/aczonin and intersectin which only have a single C2 domain. C2 domains with a calcium binding region have negatively charged residues, primarily aspartates, that serve as ligands for calcium ions.

1225-1619 5.44e-38

Dock Homology Region 2, a GEF domain, of Class B Dedicator of Cytokinesis 4; Dock4 is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates small GTPases by exchanging bound GDP for free GTP. It plays a role in regulating dendritic growth and branching in hippocampal neurons, where it is highly expressed. It may also regulate spine morphology and synapse formation. Dock4 activates the Ras family GTPase Rap1, probably indirectly through interaction with Rap regulatory proteins. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class B includes Dock3 and 4. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of Dock4, which contains the catalytic GEF activity for Rac and/or Cdc42. Class B DOCKs also contain an SH3 domain at the N-terminal region and a PxxP motif at the C-terminus.

Dock Homology Region 2, a GEF domain, of Class B Dedicator of Cytokinesis 3; Dock3, also called modifier of cell adhesion (MOCA), is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates small GTPases by exchanging bound GDP for free GTP. Dock3 is a specific GEF for Rac. It regulates N-cadherin dependent cell-cell adhesion, cell polarity, and neuronal morphology. It promotes axonal growth by stimulating actin polymerization and microtubule assembly. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class B includes Dock3 and 4. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of Dock3, which contains the catalytic GEF activity for Rac and/or Cdc42. Class B DOCKs also contain an SH3 domain at the N-terminal region and a PxxP motif at the C-terminus.

Dock Homology Region 2, a GEF domain, of Class C Dedicator of Cytokinesis 6; Dock6, also called Zizimin-related 1 (Zir1), is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates the small GTPases Rac and Cdc42 by exchanging bound GDP for free GTP. It is widely expressed and shows highest expression in the dorsal root ganglion and the brain. It regulates neurite outgrowth. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class C includes Dock6, 7 and 8. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of Dock6, which contains the catalytic GEF activity for Rac and/or Cdc42.

Dock Homology Region 2, a GEF domain, of Class C Dedicator of Cytokinesis 8; Dock8, also called Zizimin-related 3 (Zir3), is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates the small GTPases Rac1 and Cdc42 by exchanging bound GDP for free GTP. Dock8 is highly expressed in the immune system and it regulates T and B cell numbers and functions. It plays essential roles in humoral immune responses and the proper formation of B cell immunological synapses. Dock8 deficiency is a primary immune deficiency that results in extreme susceptibility to cutaneous viral infections, elevated IgE levels, and eosinophilia. It was originally described as an autosomal recessive form of hyper IgE syndrome (AR-HIES). DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class C includes Dock6, 7 and 8. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of Dock8, which contains the catalytic GEF activity for Rac and/or Cdc42.

They are divided into four classes (A-D) based on sequence similarity and domain architecture; class C, also called the Zizimin-related (Zir) subfamily, includes Dock6, 7 and 8. Class C DOCKs have been shown to have GEF activity for both Rac and Cdc42. Dock6 regulates neurite outgrowth. Dock7 plays a critical roles in the early stages of axon formation, neuronal polarity, and myelination. Dock8 regulates T and B cell numbers and functions, and plays essential roles in humoral immune responses and the proper formation of B cell immunological synapses. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker).

Dock Homology Region 2, a GEF domain, of Class D Dedicator of Cytokinesis 10; Dock10, also called Zizimin3, is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates the small GTPase Cdc42 by exchanging bound GDP for free GTP. Dock10 is preferentially expressed in lymphocytes and may play a role in interleukin-4 induced activation of B cells. It may also play a role in the invasion of tumor cells. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class D includes Dock9, 10 and 11. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate. This alignment model represents the DHR-2 domain of Dock10, which contains the catalytic GEF activity for Cdc42. Class D DOCKs also contain a Pleckstrin homology (PH) domain at the N-terminus.

DHR-2, Lobe A; This entry represents a conserved region within a number of eukaryotic dedicator of cytokinesis proteins (DOCK), which are guanine nucleotide exchange factors (GEFs), that activate some small GTPases by exchanging bound GDP for free GTP such as Rac. These proteins have a DOCK-homology region 1 (DHR-1, also known as DOCK-type C2 domain) at the N-terminus and a DHR-2 (also known as DOCKER domain) at the C-terminal. The DHR-2 is a GEF catalytic domain organized into three lobes, A, B and C, with the Rho-family binding site and catalytic centre generated entirely from lobes B and C. This entry represents Lobe A, formed from an antiparallel array of alpha helices that adopts a tetratricopeptide repeat-like fold, which through extensive contacts with lobe B, stabilizes DHR-2 domain.

Dock Homology Region 2, a GEF domain, of Class D Dedicator of Cytokinesis 11; Dock11, also called Zizimin2 or activated Cdc42-associated GEF (ACG), is an atypical guanine nucleotide exchange factor (GEF) that lacks the conventional Dbl homology (DH) domain. As a GEF, it activates the small GTPase Cdc42 by exchanging bound GDP for free GTP. Dock11 is predominantly expressed in lymphocytes and is found in high levels in germinal center B lymphocytes after T cell dependent antigen immunization. DOCK proteins are divided into four classes (A-D) based on sequence similarity and domain architecture; class D includes Dock9, 10 and 11. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker).

Src Homology 3 domain of Class A and B Dedicator of Cytokinesis proteins; DOCK proteins are atypical guanine nucleotide exchange factors (GEFs) that lack the conventional Dbl homology (DH) domain. They are divided into four classes (A-D) based on sequence similarity and domain architecture: class A includes Dock1, 2 and 5; class B includes Dock3 and 4; class C includes Dock6, 7, and 8; and class D includes Dock9, 10 and 11. All DOCKs contain two homology domains: the DHR-1 (Dock homology region-1), also called CZH1 (CED-5, Dock180, and MBC-zizimin homology 1), and DHR-2 (also called CZH2 or Docker). The DHR-1 domain binds phosphatidylinositol-3,4,5-triphosphate while DHR-2 contains the catalytic activity for Rac and/or Cdc42. This subfamily includes only Class A and B DOCKs, which also contain an SH3 domain at the N-terminal region and a PxxP motif at the C-terminus. Class A/B DOCKs are mostly specific GEFs for Rac, except Dock4 which activates the Ras family GTPase Rap1, probably indirectly through interaction with Rap regulatory proteins. The SH3 domain of class A/B DOCKs have been shown to bind Elmo, a scaffold protein that promotes GEF activity of DOCKs by releasing DHR-2 autoinhibition by the intramolecular SH3 domain. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

DHR-2, Lobe C; DOCK (dedicator of cytokinesis) proteins are guanine nucleotide exchange factors (GEFs) that activate some small GTPases, such as Rac or Cdc42, by exchanging bound GDP for free GTP to control cell migration, morphogenesis, and phagocytosis. These proteins share a DOCK-type C2 domain (also termed the DOCK-homology region (DHR)-1) at the N-terminal, and the DHR-2 domain (also termed the DOCKER domain) at the C-terminal. DHR-2 is the GEF catalytic domain organized into three lobes A, B and C, with the Rho-family binding site and catalytic centre generated entirely from lobes B and C. This entry represents Lobe C which form an antiparallel four alpha-helical bundle and contains a loop known as the nucleotide sensor characterized by a conserved valine residue essential for catalytic activity.

9-67 3.52e-03

Second Src Homology 3 domain of Vinexin, also called Sorbin and SH3 domain containing 3 (Sorbs3); Vinexin is also called Sorbs3, SH3P3, and SH3-containing adapter molecule 1 (SCAM-1). It is an adaptor protein containing one sorbin homology (SoHo) and three SH3 domains. Vinexin was first identified as a vinculin binding protein; it is co-localized with vinculin at cell-ECM and cell-cell adhesion sites. There are several splice variants of vinexin: alpha, which contains the SoHo and three SH3 domains and displays tissue-specific expression; and beta, which contains only the three SH3 domains and is widely expressed. Vinexin alpha stimulates the accumulation of F-actin at focal contact sites. Vinexin also promotes keratinocyte migration and wound healing. The SH3 domains of vinexin have been reported to bind a number of ligands including vinculin, WAVE2, DLG5, Abl, and Cbl. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

25-66 4.40e-03

Src homology 3 domain of JNK-interacting proteins 1 and 2, and similar domains; JNK-interacting proteins (JIPs) function as scaffolding proteins for c-Jun N-terminal kinase (JNK) signaling pathways. They bind to components of Mitogen-activated protein kinase (MAPK) pathways such as JNK, MKK, and several MAP3Ks such as MLK and DLK. There are four JIPs (JIP1-4); all contain a JNK binding domain. JIP1 and JIP2 also contain SH3 and Phosphotyrosine-binding (PTB) domains. Both are highly expressed in the brain and pancreatic beta-cells. JIP1 functions as an adaptor linking motor to cargo during axonal transport and also is involved in regulating insulin secretion. JIP2 form complexes with fibroblast growth factor homologous factors (FHFs), which facilitates activation of the p38delta MAPK. The SH3 domain of JIP1 homodimerizes at the interface usually involved in proline-rich ligand recognition, despite the lack of this motif in the domain itself. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.
