Ezrin/radixin/moesin family C terminal; This entry represents the C-terminal domain of the ERM family of proteins which consists of three closely-related proteins, ezrin, radixin and moesin. These proteins link actin filaments of cell surface structures to the plasma membrane, using a C-terminal F-actin binding segment and an N-terminal FERM domain (pfam00373), a common membrane binding module. Ezrin was first identified as a constituent of microvilli, radixin as a barbed, end-capping actin-modulating protein from isolated junctional fractions and moesin as a heparin binding protein. A tumour suppressor molecule responsible for neurofibromatosis type 2 (NF2) is highly similar to ERM proteins and has been designated merlin (moesin-ezrin-radixin-like protein). This entry represents the C-terminal actin-binding tail domain. This entry also includes Ermin proteins, oligodendrocyte-specific proteins associated with the cytoskeleton whose C-terminal domain is similar to that in ERM family.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in the ERM family proteins, Ezrin, Radixin, and Moesin; The ezrin-radixin-moesin (ERM) family includes a group of closely related cytoskeletal proteins that plays an essential role in microvilli formation, T-cell activation, and tumor metastasis through providing a regulated linkage between F-actin and membrane-associated proteins. These proteins may also function in signaling cascades that regulate the assembly of actin stress fibers. The ERM proteins consist of an N-terminal FERM domain, a coiled-coil (CC) domain and a C-terminal tail segment (C-tail) containing a well-defined actin-binding motif. They exist in two states, a dormant state in which the FERM domain binds to its own C-terminal tail and thereby precludes binding of some partner proteins, and an activated state, in which the FERM domain binds to one of many membrane binding proteins and the C-terminal tail binds to F-actin. The 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).

Ezrin/radixin/moesin, alpha-helical domain; The ERM family consists of three closely-related proteins, ezrin, radixin and moesin. Ezrin was first identified as a constituent of microvilli, radixin as a barbed, end-capping actin-modulating protein from isolated junctional fractions, and moesin as a heparin binding protein. A tumour suppressor molecule responsible for neurofibromatosis type 2 (NF2) is highly similar to ERM proteins and has been designated merlin (moesin-ezrin-radixin-like protein). ERM molecules contain 3 domains, an N-terminal globular domain, an extended alpha-helical domain and a charged C-terminal domain (pfam00769). Ezrin, radixin and merlin also contain a polyproline linker region between the helical and C-terminal domains. The N-terminal domain is highly conserved and is also found in merlin, band 4.1 proteins and members of the band 4.1 superfamily, designated the FERM domain. ERM proteins crosslink actin filaments with plasma membranes. They co-localize with CD44 at actin filament plasma membrane interaction sites, associating with CD44 via their N-terminal domains and with actin filaments via their C-terminal domains. This is the alpha-helical domain, which is involved in intramolecular masking of protein-protein interaction sites, regulating the activity of this proteins.

FERM domain C-lobe/F3 of the ERM family; The ERM family includes ezrin, radixin, moesin and merlin. They are composed of a N-terminal FERM (ERM) domain (also called N-ERMAD (N-terminal ERM association domain)), a coiled coil region (CRR), and a C-terminal domain CERMAD (C-terminal ERM association domain) which has an F-actin-binding site (ABD). Two actin-binding sites have been identified in the middle and N-terminal domains. Merlin is structurally similar to the ERM proteins, but instead of an actin-binding domain (ABD), it contains a C-terminal domain (CTD), just like the proteins from the 4.1 family. Activated ezrin, radixin and moesin are thought to be involved in the linking of actin filaments to CD43, CD44, ICAM1-3 cell adhesion molecules, various membrane channels and receptors, such as the Na+/H+ exchanger-3 (NHE3), cystic fibrosis transmembrane conductance regulator (CFTR), and the beta2-adrenergic receptor. The ERM proteins exist in two states, a dormant state in which the FERM domain binds to its own C-terminal tail and thereby precludes binding of some partner proteins, and an activated state, in which the FERM domain binds to one of many membrane binding proteins and the C-terminal tail binds to F-actin. 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 of ERM 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.

The ERM proteins consist of an N-terminal FERM domain, a coiled-coil (CC) domain and a C-terminal tail segment (C-tail) containing a well-defined actin-binding motif. The C-terminal domain can fold back to bind to the FERM domain forming an autoinhibited conformation. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). Ezrin is a tyrosine kinase substrate that functions as a cross-linker between actin cytoskeleton and plasma membrane. It has been implicated in the regulation of the proliferation, apoptosis, adhesion, invasion, metastasis and angiogenesis of cancer cells.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in the ERM family proteins; The ezrin-radixin-moesin (ERM) family includes a group of closely related cytoskeletal proteins that play an essential role in microvilli formation, T-cell activation, and tumor metastasis through providing a regulated linkage between F-actin and membrane-associated proteins. These proteins may also function in signaling cascades that regulate the assembly of actin stress fibers. The ERM proteins consist of an N-terminal FERM domain, a coiled-coil (CC) domain and a C-terminal tail segment (C-tail) containing a well-defined actin-binding motif. They exist in two states, a dormant state in which the FERM domain binds to its own C-terminal tail and thereby precludes binding of some partner proteins, and an activated state, in which the FERM domain binds to one of many membrane binding proteins and the C-terminal tail binds to F-actin. The 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). Merlin, which is highly related to the members of the ezrin, radixin, and moesin (ERM) protein family that are directly attached to and functionally linked with NHE1, is included in this family.

Ezrin/radixin/moesin family C terminal; This entry represents the C-terminal domain of the ERM family of proteins which consists of three closely-related proteins, ezrin, radixin and moesin. These proteins link actin filaments of cell surface structures to the plasma membrane, using a C-terminal F-actin binding segment and an N-terminal FERM domain (pfam00373), a common membrane binding module. Ezrin was first identified as a constituent of microvilli, radixin as a barbed, end-capping actin-modulating protein from isolated junctional fractions and moesin as a heparin binding protein. A tumour suppressor molecule responsible for neurofibromatosis type 2 (NF2) is highly similar to ERM proteins and has been designated merlin (moesin-ezrin-radixin-like protein). This entry represents the C-terminal actin-binding tail domain. This entry also includes Ermin proteins, oligodendrocyte-specific proteins associated with the cytoskeleton whose C-terminal domain is similar to that in ERM family.

Ras-associating (RA) domain, FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F0/F1 sub-domain, structurally similar to a beta-grasp ubiquitin-like fold; RA domain-containing proteins function by interacting, directly or indirectly, with Ras proteins and are involved in several different functions ranging from tumor suppression to being oncoproteins. Ras protein is a small GTPase that is involved in cellular signal transduction. The RA domain has the beta-grasp ubiquitin-like (Ubl) fold with low sequence similarity to ubiquitin (Ub). Ub is a protein modifier in eukaryotes that is involved in various cellular processes, including transcriptional regulation, cell cycle control, and DNA repair in eukaryotes. RA-containing proteins include RalGDS, AF6, RIN, RASSF1, SNX27, CYR1, STE50, and phospholipase C epsilon. The FERM domain is present at the N-terminus of a large and diverse group of proteins that mediate linkage of the cytoskeleton to the plasma membrane. FERM-containing proteins are ubiquitous components of the cytocortex and are involved in cell transport, cell structure and signaling. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, also known as the N-terminal Ubl-like structural domain of the FERM domain (FERM_N), which is structurally similar to Ub. Some FERM domain-containing proteins contain an N-terminal region, which also has the beta-grasp Ub-like fold, precedes the FERM domain and has been referred to as the F0 domain.

FERM domain C-lobe; 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.

FERM domain C-lobe of FERM domain-containing protein 4A and 4B (FRMD4A and 4B); FRMD4A is part of the Par-3/FRMD4A/cytohesin-1 complex that activates Arf6, a central player in actin cytoskeleton dynamics and membrane trafficking, during junctional remodeling and epithelial polarization. The Par-3/Par-6/aPKC/Cdc42 complex regulates the conversion of primordial adherens junctions (AJs) into belt-like AJs and the formation of linear actin cables. When primordial AJs are formed, Par-3 recruits scaffolding protein FRMD4A which connects Par-3 and the Arf6 guanine-nucleotide exchange factor (GEF), cytohesin-1. FRMD4B (also called GRP1-binding protein, GRSP1) is a novel member of GRP1 signaling complexes that are recruited to plasma membrane ruffles in response to insulin receptor signaling. The GRSP1/FRMD4B protein contains a FERM protein domain as well as two coiled coil domains and may function as a scaffolding protein. GRP1 and GRSP1 interact through the coiled coil domains in the two proteins. 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.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in FERM domain-containing protein 3 (FRMD3) and similar proteins; FRMD3, also termed band 4.1-like protein 4O, or ovary type protein 4.1 (4.1O), belongs to the 4.1 protein superfamily, which share the highly conserved membrane-association FERM domain. The 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). FRMD3 is involved in maintaining cell shape and integrity. It also functions as a tumour suppressor in non-small cell lung carcinoma (NSCLC). Some single nucleotide polymorphisms (SNPs) located in FRMD3 have been associated with diabetic kidney disease (DKD) in different ethnicities.

FERM domain C-lobe of FERM domain-containing protein 3 and 5 (FRMD3 and 5); FRMD3 (also called Band 4.1-like protein 4O/4.1O though it is not a true member of that family) is a novel putative tumor suppressor gene that is implicated in the origin and progression of lung cancer. In humans there are 5 isoforms that are produced by alternative splicing. Less is known about FRMD5, though there are 2 isoforms of the human protein are produced by alternative splicing. Both FRMD3 and FRMD5 contain a N-terminal FERM domain, followed by a FERM adjacent (FA) domain, and 4.1 protein C-terminal domain (CTD). 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.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in erythrocyte membrane protein band 4.1-like protein 1 (EPB41L1) and similar proteins; EPB41L1, also termed neuronal protein 4.1 (4.1N), belongs to the skeletal protein 4.1 family that is involved in cellular processes such as cell adhesion, migration and signaling. It is a cytoskeleton-associated protein that may serve as a tumor suppressor in solid tumors. It suppresses hypoxia-induced epithelial-mesenchymal transition in epithelial ovarian cancer (EOC) cells. The down-regulation of EPB41L1 expression is a critical step for non-small cell lung cancer (NSCLC) development. Moreover, EPB41L1 functions as a linker protein between inositol 1,4,5-trisphosphate receptor type1 (IP3R1) and actin filaments in neurons. EPB41L1 contains a FERM domain, a spectrin and actin binding (SAB) domain, and a C-terminal domain. The 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).

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in E3 ubiquitin-protein ligase MYLIP and similar proteins; MYLIP, also termed inducible degrader of the LDL-receptor (Idol), or myosin regulatory light chain interacting protein (MIR), is an E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of myosin regulatory light chain (MRLC), LDLR, VLDLR and LRP8. Its activity depends on E2 ubiquitin-conjugating enzymes of the UBE2D family, including UBE2D1, UBE2D2, UBE2D3, and UBE2D4. MYLIP stimulates clathrin-independent endocytosis and acts as a sterol-dependent inhibitor of cellular cholesterol uptake by binding directly to the cytoplasmic tail of the LDLR and promoting its ubiquitination via the UBE2D1/E1 complex. The ubiquitinated LDLR then enters the multivesicular body (MVB) protein-sorting pathway and is shuttled to the lysosome for degradation. Moreover, MYLIP has been identified as a novel ERM-like protein that affects cytoskeleton interactions regulating cell motility, such as neurite outgrowth. The ERM proteins includes ezrin, radixin, and moesin, which are cytoskeletal effector proteins linking actin to membrane-bound proteins at the cell surface. MYLIP contains a FERM-domain and a C-terminal C3HC4-type RING-HC finger. The 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).

FERM domain C-lobe of FERM, RhoGEF and pleckstrin domain-containing protein 1 and related proteins; Members here include FARP1 (also called Chondrocyte-derived ezrin-like protein; PH domain-containing family C member 2), FARP2 (also called FIR/FERM domain including RhoGEF; FGD1-related Cdc42-GEF/FRG), and FRMD7(FERM domain containing 7). FARP1 and FARP2 are members of the Dbl family guanine nucleotide exchange factors (GEFs) which are upstream positive regulators of Rho GTPases. FARP1 has increased expression in differentiated chondrocytes. FARP2 is thought to regulate neurite remodeling by mediating the signaling pathways from membrane proteins to Rac. It is found in brain, lung, and testis, as well as embryonic hippocampal and cortical neurons. These members are composed of a N-terminal FERM domain, a proline-rich (PR) domain, Dbl-homology (DH), and two C-terminal PH domains. Other members in this family do not contain the DH domains such as the Human FERM domain containing protein 7 and Caenorhabditis elegans CFRM3, both of which have unknown functions. They contain an N-terminal FERM domain, a PH domain, followed by a FA (FERM adjacent) domain. 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.
