86-197 | 2.85e-75 | ||||
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. Both F0 and F1 domains have similar ubiquitin-like folds. This family corresponds to the F1 domain. : Pssm-ID: 340693 Cd Length: 112 Bit Score: 245.40 E-value: 2.85e-75

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. : Pssm-ID: 462691 Cd Length: 161 Bit Score: 225.24 E-value: 1.45e-67

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. : Pssm-ID: 430312 Cd Length: 125 Bit Score: 206.72 E-value: 1.40e-61

309-400 | 4.59e-57 | ||||
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. : Pssm-ID: 269973 Cd Length: 92 Bit Score: 192.56 E-value: 4.59e-57

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 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.
