FERM domain C-lobe of Novel band 4.1-like protein 4 and 5 (NBL4 and 5); NBL4 (also called Erythrocyte protein band 4.1-like 4; Epb4 1l4) plays a role the beta-catenin/Tcf signaling pathway and is thought to be involved in establishing the cell polarity or proliferation. NBL4 may be also involved in adhesion, in cell motility and/or in cell-to-cell communication. No role for NBL5 has been proposed to date. Both NBL4 and NBL5 contain a N-terminal FERM domain which 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 is a member of the PH superfamily. 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 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, 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.

FERM domain C-lobe of Protein 4.1 family; The protein 4.1 family includes four well-defined members: erythroid protein 4.1 (4.1R), the best known and characterized member, 4.1G (general), 4.1N (neuronal), and 4.1 B (brain). The less well understood 4.1O/FRMD3 is not a true member of this family and is not included in this hierarchy. Besides three highly conserved domains, FERM, SAB (spectrin and actin binding domain) and CTD (C-terminal domain), the proteins from this family contain several unique domains: U1, U2 and U3. FERM domains like other members of the FERM domain superfamily have a cloverleaf architecture with three distinct lobes: (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 brain is a particularly rich source of protein 4.1 isoforms. The various 4.1R, 4.1G, 4.1N, and 4.1B mRNAs are all expressed in distinct patterns within the brain. It is likely that 4.1 proteins play important functional roles in the brain including motor coordination and spatial learning, postmitotic differentiation, and synaptic architecture and function. In addition they are found in nonerythroid, nonneuronal cells where they may play a general structural role in nuclear architecture and/or may interact with splicing factors. The FERM C domain is the third structural domain within the FERM domain. 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 tyrosine-protein phosphatase non-receptor type 4 (PTPN4); PTPN4, also termed protein-tyrosine phosphatase MEG1 (MEG) or PTPase-MEG1, belongs to the non-transmembrane FERM-containing protein-tyrosine phosphatase (PTP) subfamily characterized by a conserved N-terminal FERM domain, a PDZ domain, and a C-terminal PTP catalytic 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). PTPN4 protects cells against apoptosis. It associates with the mitogen-activated protein kinase p38gamma (also known as MAPK12) to form a PTPN4-p38gamma complex that promotes cellular signaling, preventing cell death induction. It also inhibits tyrosine phosphorylation and subsequent cytoplasm translocation of TRIF-related adaptor molecule (TRAM, also known as TICAM2), resulting in the disturbance of TRAM-TRIF interaction. Moreover, PTPN4 negatively regulates cell proliferation and motility through dephosphorylation of CrkI.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in tyrosine-protein phosphatase non-receptor type 3 (PTPN3); PTPN3, also termed protein-tyrosine phosphatase H1 (PTP-H1), belongs to the non-transmembrane FERM-containing protein-tyrosine phosphatase (PTP) subfamily characterized by a conserved N-terminal FERM domain, a PDZ domain, and a C-terminal PTP catalytic 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). PTPN3 associates with the mitogen-activated protein kinase p38gamma (also known as MAPK12) to form a PTPN3-p38gamma complex that promotes Ras-induced oncogenesis. It may also act as a tumor suppressor in lung cancer through its modulation of epidermal growth factor receptor (EGFR) signaling. Moreover, PTPN3 shows sensitizing effect to anti-estrogens. It dephosphorylates the tyrosine kinase EGFR, disrupts its interaction with the nuclear estrogen receptor, and increases breast cancer sensitivity to small molecule tyrosine kinase inhibitors (TKIs). It also cooperates with vitamin D receptor to stimulate breast cancer growth through their mutual stabilization.

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.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in tyrosine-protein phosphatase non-receptor type 14 (PTPN14) and similar proteins; PTPN14, also termed protein-tyrosine phosphatase pez, or PTPD2, or PTP36, is a widely expressed non-transmembrane cytosolic protein tyrosine phosphatase (PTP). It belongs to the FERM family of PTPs characterized by a conserved N-terminal FERM domain and a C-terminal PTP catalytic domain with an intervening sequence containing an acidic region and a putative SH3 domain-binding sequence. 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). PTPN14 plays a role in the nucleus during cell proliferation. It forms a complex with Kibra and LATS1 proteins and negatively regulates the key Hippo pathway protein Yes-associated protein (YAP) oncogenic function by controlling its localization. It specifically regulates p130 Crk-associated substrate (p130Cas) phosphorylation at tyrosine residue 128 (Y128) in colorectal cancer (CRC) cells. Moreover, PTPN14 may be a critical enzyme in regulating endothelial cell function. It plays a crucial role in organogenesis by inducing transforming growth factor beta (TGFbeta) and epithelial-mesenchymal transition (EMT). It also acts as a modifier of angiogenesis and hereditary haemorrhagic telangiectasia. It regulates the lymphatic function and choanal development through the interaction with the vascular endothelial growth factor receptor 3 (VEGFR3), a receptor tyrosine kinase essential for lymphangiogenesis. Furthermore, PTPN14 functions as a regulator of cell motility through its action on cell-cell adhesion. Beta-Catenin, a central component of adherens junctions, has been identified as a PTPN14 substrate. PTPN14 works as a novel sperm-motility biomarker and a potential mitochondrial protein.

FERM domain C-lobe of Protein tyrosine phosphatase non-receptor 13 (PTPH13); There are many functions of PTPN13 (also called PTPL1, PTP-BAS, hPTP1E, FAP1, or PTPL1). Mice lacking PTPN13 activity have abnormal regulation of signal transducer and activator of transcription signaling in their T cells, mild impairment of motor nerve repair, and a significant reduction in the growth of retinal glia cultures. It also plays a role in adipocyte differentiation. PTPN13 contains a kinase non-catalytic C-lobe domain (KIND), a FERM domain with two potential phosphatidylinositol 4,5-biphosphate [PtdIns(4,5)P2]-binding motifs, 5 PDZ domains, and a carboxy-terminal catalytic domain. There is an nteraction between the FERM domain of PTPL1 and PtdIns(4,5)P2 which is thought to regulate the membrane localization of PTPN13. PDZ are protein/protein interaction domains so there is the potential for numerous partners that can actively participate in the regulation of its phosphatase activity or can permit direct or indirect recruitment of tyrosine phosphorylated PTPL1 substrates. 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.

This family corresponds to F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). Moesin is involved in mitotic spindle function through stabilizing cell shape and microtubules at the cell cortex. It is required for the formation of F-actin networks that mediate endosome biogenesis or maturation and transport through the degradative pathway.

FERM domain C-lobe of E3 ubiquitin ligase myosin regulatory light chain-interacting protein (MYLIP; also called inducible degrader of the LDL receptor, IDOL); MYLIP/IDOL is a regulator of the LDL receptor (LDLR) pathway via the nuclear receptor liver X receptor (LXR). In response to cellular cholesterol loading, the activation of LXR leads to the induction of MYLIP expression. MYLIP stimulates ubiquitination of the LDLR on its cytoplasmic tail, directing its degradation. The LXR-MYLIP-LDLR pathway provides a complementary pathway to sterol regulatory element-binding proteins for the feedback inhibition of cholesterol uptake. MYLIP has an N-terminal FERM domain and in some cases a C-terminal RING 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.

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. 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.
