90-201 1.60e-73

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in Talin-2 (TLN2); TLN2 is a cytoskeletal protein that plays an important role in cell adhesion and recycling of synaptic vesicles. TLN2 is required for myoblast fusion, sarcomere assembly and the maintenance of myotendinous junctions. TLN2 consists of an N-terminal head and a C-terminal rod. The talin head harbors a FERM (Band 4.1, ezrin, radixin, moesin) domain made up of F1, F2 and F3 domains, as well as an N-terminal region that precedes the FERM domain and has been referred to as the F0 domain. Both F0 and F1 domains have similar ubiquitin-like folds. This family corresponds to the F1 domain.

496-657 1.38e-69

Talin, middle domain; Members of this family adopt a structure consisting of five alpha helices that fold into a bundle. They contain a Vinculin binding site (VBS) composed of a hydrophobic surface spanning five turns of helix four. Activation of the VBS causes subsequent recruitment of Vinculin, which enables maturation of small integrin/talin complexes into more stable adhesions. Formation of the complex between VBS and Vinculin requires prior unfolding of this middle domain: once released from the talin hydrophobic core, the VBS helix is then available to induce the 'bundle conversion' conformational change within the vinculin head domain thereby displacing the intramolecular interaction with the vinculin tail, allowing vinculin to bind actin.

314-405 8.02e-60

FERM domain C-lobe/F3 of Talin; Talin (also called filopodin) plays an important role in initiating actin filament growth in motile cell protrusions. It is responsible for linking the cytoplasmic domains of integrins to the actin-based cytoskeleton, and is involved in vinculin, integrin and actin interactions. At the leading edge of motile cells, talin colocalises with the hyaluronan receptor layilin in transient adhesions, some of which become more stable focal adhesions (FA). During this maturation process, layilin is replaced with integrins, where localized production of PI(4,5)P(2) by type 1 phosphatidyl inositol phosphate kinase type 1gamma (PIPK1gamma) is thought to play a role in FA assembly. Talins are composed of a N-terminal region FERM domain which us made up of 3 subdomains (N, alpha-, and C-lobe; or- A-lobe, B-lobe, and C-lobe; or F1, F2, and F3) connected by short linkers, a talin rod which binds vinculin, and a conserved C-terminal region with actin- and integrin-binding sites. There are 2 additional actin-binding domains, one in the talin rod and the other in the FERM domain. Both the F2 and F3 FERM subdomains contribute to F-actin binding. Subdomain F3 of the FERM domain contains overlapping binding sites for integrin cytoplasmic domains and for the type 1 gamma isoform of PIP-kinase (phosphatidylinositol 4-phosphate 5-kinase). The FERM domain has a cloverleaf tripart structure . F3 within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs) , the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

1852-1936 3.59e-37

Vinculin Binding Site; Vinculin binding sites are predominantly found in talin and talin-like molecules, enabling binding of vinculin to talin, stabilising integrin-mediated cell-matrix junctions. Talin, in turn, links integrins to the actin cytoskeleton. The consensus sequence for Vinculin binding sites is LxxAAxxVAxxVxxLIxxA, with a secondary structure prediction of four amphipathic helices. The hydrophobic residues that define the VBS are themselves 'masked' and are buried in the core of a series of helical bundles that make up the talin rod.

TLN2 is required for myoblast fusion, sarcomere assembly and the maintenance of myotendinous junctions. TLN2 consists of an N-terminal head and a C-terminal rod. The talin head harbors a FERM (Band 4.1, ezrin, radixin, moesin) domain made up of F1, F2 and F3 domains, as well as an N-terminal region that precedes the FERM domain and has been referred to as the F0 domain. Both F0 and F1 domains have similar ubiquitin-like folds. This family corresponds to the F1 domain.

496-657 1.38e-69

Talin, middle domain; Members of this family adopt a structure consisting of five alpha helices that fold into a bundle. They contain a Vinculin binding site (VBS) composed of a hydrophobic surface spanning five turns of helix four. Activation of the VBS causes subsequent recruitment of Vinculin, which enables maturation of small integrin/talin complexes into more stable adhesions. Formation of the complex between VBS and Vinculin requires prior unfolding of this middle domain: once released from the talin hydrophobic core, the VBS helix is then available to induce the 'bundle conversion' conformational change within the vinculin head domain thereby displacing the intramolecular interaction with the vinculin tail, allowing vinculin to bind actin.

314-405 8.02e-60

FERM domain C-lobe/F3 of Talin; Talin (also called filopodin) plays an important role in initiating actin filament growth in motile cell protrusions. It is responsible for linking the cytoplasmic domains of integrins to the actin-based cytoskeleton, and is involved in vinculin, integrin and actin interactions. At the leading edge of motile cells, talin colocalises with the hyaluronan receptor layilin in transient adhesions, some of which become more stable focal adhesions (FA). During this maturation process, layilin is replaced with integrins, where localized production of PI(4,5)P(2) by type 1 phosphatidyl inositol phosphate kinase type 1gamma (PIPK1gamma) is thought to play a role in FA assembly. Talins are composed of a N-terminal region FERM domain which us made up of 3 subdomains (N, alpha-, and C-lobe; or- A-lobe, B-lobe, and C-lobe; or F1, F2, and F3) connected by short linkers, a talin rod which binds vinculin, and a conserved C-terminal region with actin- and integrin-binding sites. There are 2 additional actin-binding domains, one in the talin rod and the other in the FERM domain. Both the F2 and F3 FERM subdomains contribute to F-actin binding. Subdomain F3 of the FERM domain contains overlapping binding sites for integrin cytoplasmic domains and for the type 1 gamma isoform of PIP-kinase (phosphatidylinositol 4-phosphate 5-kinase). The FERM domain has a cloverleaf tripart structure . F3 within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs) , the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

Vinculin Binding Site; Vinculin binding sites are predominantly found in talin and talin-like molecules, enabling binding of vinculin to talin, stabilising integrin-mediated cell-matrix junctions. Talin, in turn, links integrins to the actin cytoskeleton. The consensus sequence for Vinculin binding sites is LxxAAxxVAxxVxxLIxxA, with a secondary structure prediction of four amphipathic helices. The hydrophobic residues that define the VBS are themselves 'masked' and are buried in the core of a series of helical bundles that make up the talin rod.

496-657 1.38e-69

Talin, middle domain; Members of this family adopt a structure consisting of five alpha helices that fold into a bundle. They contain a Vinculin binding site (VBS) composed of a hydrophobic surface spanning five turns of helix four. Activation of the VBS causes subsequent recruitment of Vinculin, which enables maturation of small integrin/talin complexes into more stable adhesions. Formation of the complex between VBS and Vinculin requires prior unfolding of this middle domain: once released from the talin hydrophobic core, the VBS helix is then available to induce the 'bundle conversion' conformational change within the vinculin head domain thereby displacing the intramolecular interaction with the vinculin tail, allowing vinculin to bind actin.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in Talin-1 (TLN1); TLN1 is a cytoskeletal protein that plays a pivotal role in regulating the activity of the integrin family of cell adhesion proteins by coupling them to F-actin. It functions as a focal adhesion protein involved in the attachment of the bacterium. It binds to multiple adhesion molecules, including integrins, vinculin, focal adhesion kinase (FAK), and actin. TLN1 also plays an essential role in integrin activation. TLN1 interacts with the hepatitis B virus (HBV) accessory protein X (HBx), which induces the degradation of TLN1. It also acts as an adaptor protein that regulates leukocyte function-associated antigen-1 (LFA-1) affinity. In addition, TLN1 is required for myoblast fusion, sarcomere assembly and the maintenance of myotendinous junctions. TLN1 consists of an N-terminal head and a C-terminal rod. The talin head harbors a FERM (Band 4.1, ezrin, radixin, moesin) domain made up of F1, F2 and F3 domains, as well as an N-terminal region that precedes the FERM domain and has been referred to as the F0 domain.

314-405 8.02e-60

FERM domain C-lobe/F3 of Talin; Talin (also called filopodin) plays an important role in initiating actin filament growth in motile cell protrusions. It is responsible for linking the cytoplasmic domains of integrins to the actin-based cytoskeleton, and is involved in vinculin, integrin and actin interactions. At the leading edge of motile cells, talin colocalises with the hyaluronan receptor layilin in transient adhesions, some of which become more stable focal adhesions (FA). During this maturation process, layilin is replaced with integrins, where localized production of PI(4,5)P(2) by type 1 phosphatidyl inositol phosphate kinase type 1gamma (PIPK1gamma) is thought to play a role in FA assembly. Talins are composed of a N-terminal region FERM domain which us made up of 3 subdomains (N, alpha-, and C-lobe; or- A-lobe, B-lobe, and C-lobe; or F1, F2, and F3) connected by short linkers, a talin rod which binds vinculin, and a conserved C-terminal region with actin- and integrin-binding sites. There are 2 additional actin-binding domains, one in the talin rod and the other in the FERM domain. Both the F2 and F3 FERM subdomains contribute to F-actin binding. Subdomain F3 of the FERM domain contains overlapping binding sites for integrin cytoplasmic domains and for the type 1 gamma isoform of PIP-kinase (phosphatidylinositol 4-phosphate 5-kinase). The FERM domain has a cloverleaf tripart structure . F3 within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs) , the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in Talin and similar proteins; Talin is a cytoskeletal protein that activates integrins and couples them to cytoskeletal actin. Talin consists of an N-terminal head and a C-terminal rod.

Both F0 and F1 domains have similar ubiquitin-like folds. This family corresponds to the F0 domain that is joined to the F1 domain in a novel fixed orientation by an extensive charged interface. It is required for maximal integrin-activation, by interacting with other FA components; no binding partner has yet been found for it.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F0 sub-domain, found in Talin-2 (TLN2); TLN2 is a cytoskeletal protein that plays an important role in cell adhesion and recycling of synaptic vesicles. TLN2 is required for myoblast fusion, sarcomere assembly and the maintenance of myotendinous junctions. TLN2 consists of an N-terminal head and a C-terminal rod. The talin head harbors a FERM (Band 4.1, ezrin, radixin, moesin) domain made up of F1, F2 and F3 domains, as well as an N-terminal region that precedes the FERM domain and has been referred to as the F0 domain. Both F0 and F1 domains have similar ubiquitin-like folds. This family corresponds to the F0 domain.

I/LWEQ domain; I/LWEQ domains bind to actin. It has been shown that the I/LWEQ domains from mouse talin and yeast Sla2p interact with F-actin. I/LWEQ domains can be placed into four major groups based on sequence similarity: (1) Metazoan talin; (2) Dictyostelium TalA/TalB and SLA110; (3) metazoan Hip1p; and (4) yeast Sla2p. The domain has four conserved blocks, the name of the domain is derived from the initial conserved amino acid of each of the four blocks.

4-89 5.83e-49

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F0 sub-domain, found in Talin-1 (TLN1); TLN1 is a cytoskeletal protein that plays a pivotal role in regulating the activity of the integrin family of cell adhesion proteins by coupling them to F-actin. It functions as a focal adhesion protein involved in the attachment of the bacterium. It binds to multiple adhesion molecules, including integrins, vinculin, focal adhesion kinase (FAK), and actin. TLN1 also plays an essential role in integrin activation. TLN1 interacts with the hepatitis B virus (HBV) accessory protein X (HBx), which induces the degradation of TLN1. It also acts as an adaptor protein that regulates leukocyte function-associated antigen-1 (LFA-1) affinity. In addition, TLN1 is required for myoblast fusion, sarcomere assembly and the maintenance of myotendinous junctions. TLN1 consists of an N-terminal head and a C-terminal rod. The talin head harbors a FERM (Band 4.1, ezrin, radixin, moesin) domain made up of F1, F2 and F3 domains, as well as an N-terminal region that precedes the FERM domain and has been referred to as the F0 domain. Both F0 and F1 domains have similar ubiquitin-like folds. This family corresponds to the F0 domain.

Vinculin Binding Site; Vinculin binding sites are predominantly found in talin and talin-like molecules, enabling binding of vinculin to talin, stabilising integrin-mediated cell-matrix junctions. Talin, in turn, links integrins to the actin cytoskeleton. The consensus sequence for Vinculin binding sites is LxxAAxxVAxxVxxLIxxA, with a secondary structure prediction of four amphipathic helices. The hydrophobic residues that define the VBS are themselves 'masked' and are buried in the core of a series of helical bundles that make up the talin rod.

FERM domain B-lobe; The FERM domain has a cloverleaf tripart structure (FERM_N, FERM_M, FERM_C/N, alpha-, and C-lobe/A-lobe, B-lobe, C-lobe/F1, F2, F3). The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases, the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the pleckstrin homology (PH) and phosphotyrosine binding (PTB) domains and consequently is capable of binding to both peptides and phospholipids at different sites.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in kindlin-2 (KIND2); KIND2, also termed fermitin family homolog 2 (FERMT2), or mitogen-inducible gene 2 protein (MIG-2), or Pleckstrin homology (PH) domain-containing family C member 1, is an adaptor protein that is widely distributed and is particularly abundant in adherent cells. It binds to the integrin beta cytoplasmic tail to promote integrin activation. It promotes carcinogenesis through regulation of cell-cell and cell-extracellular matrix adhesion. KIND2 also plays an important role in cardiac development. KIND2 consists of an atypical FERM domain that is made up of F1, F2 and F3 domains, as well as an N-terminal region, which precedes the FERM domain and has been referred to as the F0 domain. This family corresponds to the F1 domain.

100-202 7.01e-07

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in kindlin-1 (KIND1); KIND1, also termed Kindlerin, or Kindler syndrome protein, or fermitin family homolog 1 (FERMT1), or Unc-112-related protein 1 (URP1), is an integrin-interacting protein that has been implicated in cell adhesion, proliferation, polarity, and motility. It is essential for maintaining the structure of cell-matrix adhesion, such as focal adhesions and podosomes. KIND1 is expressed primarily in epithelial cells. Loss or mutations of KIND1 gene may cause the Kindler syndrome (KS), an autosomal recessive skin disorder with an intriguing progressive phenotype comprising skin blistering, photosensitivity, progressive poikiloderma with extensive skin atrophy, and propensity to skin cancer. KIND1 forms a molecular complex with the key transforming growth factor (TGF)-beta/Smad3 signaling components including type I TGFbeta receptor (TbetaRI), Smad3 and Smad anchor for receptor activation (SARA) to control the activation of TGF-beta/Smad3 signaling pathway. KIND1 consists of an atypical FERM domain that is made up of F1, F2 and F3 domains, as well as an N-terminal region, which precedes the FERM domain and has been referred to as the F0 domain. This family corresponds to the F1 domain.

313-401 3.17e-04

FERM domain C-lobe of the Fermitin family; Fermitin functions as a mediator of integrin inside-out signalling. The recruitment of Fermitin proteins and Talin to the membrane mediates the terminal event of integrin signalling, via interaction with integrin beta subunits. Fermatin has FERM domain interrupted with a pleckstrin homology (PH) domain. Fermitin family homologs (Fermt1, 2, and 3, also known as Kindlins) are each encoded by a different gene. In mammalian studies, Fermt1 is generally expressed in epithelial cells, Fermt2 is expressed inmuscle tissues, and Fermt3 is expressed in hematopoietic lineages. Specifically Fermt2 is expressed in smooth and striated muscle tissues in mice and in the somites (a trunk muscle precursor) and neural crest in Xenopus embryos. As such it has been proposed that Fermt2 plays a role in cardiomyocyte and neural crest differentiation. Expression of mammalian Fermt3 is associated with hematopoietic lineages: the anterior ventral blood islands, vitelline veins, and early myeloid cells. In Xenopus embryos this expression, also include the notochord and cement gland. The FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). This cd is not included in the C-lobe hierarchy based on its position in the tree. One thing to note is that unlike the other members of the C-lobe hierarchy it contains 2 FERM M domains which might also reflect a difference in its evolutionary history. The C-lobe/F3 within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs), the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in kindlin-3 (KIND3); KIND3, also termed fermitin family homolog 3 (FERMT3), or MIG2-like protein, or Unc-112-related protein 2, is an adaptor protein that expressed primarily in hematopoietic cells. It plays a central role in cell adhesion in hematopoietic cells, and also promotes integrin activation, clustering and outside-in signaling. KIND3, together with talin-1, contributes essentially to the activation of beta2-integrins in neutrophils. In addition, KIND3 interacts with the ribosome and regulates c-Myc expression required for proliferation of chronic myeloid leukemia cells. Mutations in the KIND3 gene cause leukocyte adhesion deficiency type III (LAD III), which is characterized by high susceptibility to infections, spontaneous and episodic bleedings, and osteopetrosis. KIND3 consists of an atypical FERM domain that is made up of F1, F2 and F3 domains, as well as an N-terminal region, which precedes the FERM domain and has been referred to as the F0 domain. This family corresponds to the F1 domain.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in Dictyostelium discoideum Myosin-VIIa (DdMyo7) and similar proteins; DdMyo7, also termed Myosin-I heavy chain, or class VII unconventional myosin, or M7, plays a role in adhesion in Dictyostelium where it is a component of a complex of proteins that serve to link membrane receptors to the underlying actin cytoskeleton. It interacts with talinA, an actin-binding protein with a known role in cell-substrate adhesion. DdMyo7 is required for phagocytosis. It is also essential for the extension of filopodia, plasma membrane protrusions filled with parallel bundles of F-actin. Members in this family contain a myosin motor domain, two MyTH4 domains, two FERM (Band 4.1, ezrin, radixin, moesin) domains, and two Pleckstrin homology (PH) domains. Some family members contain an extra SH3 domain. Each FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

334-395 3.48e-03

Downstream of tyrosine kinase 4, 5, and 6 proteins phosphotyrosine-binding domain (PTBi); The Dok family adapters are phosphorylated by different protein tyrosine kinases. Dok proteins are involved in processes such as modulation of cell differentiation and proliferation, as well as in control of the cell spreading and migration The Dok protein contains an N-terminal pleckstrin homology (PH) domain followed by a central phosphotyrosine binding (PTB) domain, which has a PH-like fold, and a proline- and tyrosine-rich C-terminal tail. The PH domain binds to acidic phospholids and localizes proteins to the plasma membrane, while the PTB domain mediates protein-protein interactions by binding to phosphotyrosine-containing motifs. The C-terminal part of Dok contains multiple tyrosine phosphorylation sites that serve as potential docking sites for Src homology 2-containing proteins such as ras GTPase-activating protein and Nck, leading to inhibition of ras signaling pathway activation and the c-Jun N-terminal kinase (JNK) and c-Jun activation, respectively. There are 7 mammalian Dok members: Dok-1 to Dok-7. Dok-1 and Dok-2 act as negative regulators of the Ras-Erk pathway downstream of many immunoreceptor-mediated signaling systems, and it is believed that recruitment of p120 rasGAP by Dok-1 and Dok-2 is critical to their negative regulation. Dok-3 is a negative regulator of the activation of JNK and mobilization of Ca2+ in B-cell receptor-mediated signaling, interacting with SHIP-1 and Grb2. Dok-4- 6 play roles in protein tyrosine kinase(PTK)-mediated signaling in neural cells and Dok-7 is the key cytoplasmic activator of MuSK (Muscle-Specific Protein Tyrosine Kinase). PTB domains have a common PH-like fold and are found in various eukaryotic signaling molecules. This domain was initially shown to binds peptides with a NPXY motif with differing requirements for phosphorylation of the tyrosine, although more recent studies have found that some types of PTB domains can bind to peptides lack tyrosine residues altogether. In contrast to SH2 domains, which recognize phosphotyrosine and adjacent carboxy-terminal residues, PTB-domain binding specificity is conferred by residues amino-terminal to the phosphotyrosine. PTB domains are classified into three groups: phosphotyrosine-dependent Shc-like, phosphotyrosine-dependent IRS-like, and phosphotyrosine-independent Dab-like PTB domains. This cd is part of the IRS-like subgroup.

314-409 6.35e-03

FERM domain C-lobe, repeat 2, of Myosin VII (MyoVII, Myo7); MyoVII, a MyTH-FERM myosin, is an actin-based motor protein essential for a variety of biological processes in the actin cytoskeleton function. Mutations in MyoVII leads to problems in sensory perception: deafness and blindness in humans (Usher Syndrome), retinal defects and deafness in mice (shaker 1), and aberrant auditory and vestibular function in zebrafish. Myosin VIIAs have plus (barbed) end-directed motor activity on actin filaments and a characteristic actin-activated ATPase activity. MyoVII consists of a conserved spectrin-like, SH3 subdomain N-terminal region, a motor/head region, a neck made of 4-5 IQ motifs, and a tail consisting of a coiled-coil domain, followed by a tandem repeat of myosin tail homology 4 (MyTH4) domains and partial FERM domains that are separated by an SH3 subdomain and are thought to mediate dimerization and binding to other proteins or cargo. Members include: MyoVIIa, MyoVIIb, and MyoVII members that do not have distinct myosin VIIA and myosin VIIB genes. The FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs), the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.
