Ras-associating (RA) domain found in growth factor receptor-bound (Grb) protein 14; Grb14, a member of cytoplasmic adaptor proteins, is a tissue-specific negative regulator of insulin signaling. RA domain has the beta-grasp ubiquitin-like fold with low sequence similarity to ubiquitin (Ub). Ubi is a protein modifier in eukaryotes that is involved in various cellular processes including transcriptional regulation, cell cycle control, and DNA repair in eukaryotes. A novel function of Grb14 RA domain is to interact with the nucleotide binding pocket of a cyclic nucleotide gated channel alpha subunit (CNGA1) and inhibits its activity. Grb7 and its related family members Grb10 and Grb14 share a conserved domain architecture that includes an amino-terminal proline-rich region, a central segment termed the GM region (for Grb and Mig) which includes the RA, PIR, and PH domains, and a carboxyl-terminal SH2 domain. Grb7/10/14 family proteins are phosphorylated on serine/threonine as well as tyrosine residues and are mainly localized to the cytoplasm. : Pssm-ID: 340556 Cd Length: 85 Bit Score: 185.81 E-value: 6.97e-60

Amyloid beta (A4) Precursor protein-Binding, family B, member 1 Interacting Protein pleckstrin homology (PH) domain; APBB1IP consists of a Ras-associated (RA) domain, a PH domain, a family-specific BPS region, and a C-terminal SH2 domain. Grb7, Grb10 and Grb14 are paralogs that are also present in this hierarchy. These adapter proteins bind a variety of receptor tyrosine kinases, including the insulin and insulin-like growth factor-1 (IGF1) receptors. Grb10 and Grb14 are important tissue-specific negative regulators of insulin and IGF1 signaling based and may contribute to type 2 (non-insulin-dependent) diabetes in humans. RA-PH function as a single structural unit and is dimerized via a helical extension of the PH domain. The PH domain here are proposed to bind phosphoinositides non-cannonically ahd are unlikely to bind an activated GTPase. The tandem RA-PH domains are present in a second adapter-protein family, MRL proteins, Caenorhabditis elegans protein MIG-1012, the mammalian proteins RIAM and lamellipodin and the Drosophila melanogaster protein Pico12, all of which are Ena/VASP-binding proteins involved in actin-cytoskeleton rearrangement. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes. : Pssm-ID: 269961 Cd Length: 124 Bit Score: 138.14 E-value: 8.36e-41

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).

Mutations in Brutons tyrosine kinase (Btk) within its PH domain cause X-linked agammaglobulinaemia (XLA) in patients. Point mutations cluster into the positively charged end of the molecule around the predicted binding site for phosphatidylinositol lipids.

Ras-associating (RA) domain found in PDZ domain-containing guanine nucleotide exchange factor 1 (PDZ-GEF1) and similar proteins; PDZ-GEF1, also termed Rap guanine nucleotide exchange factor 2, or cyclic nucleotide ras GEF (CNrasGEF), or neural RAP guanine nucleotide exchange protein (nRap GEP), or Ras/Rap1-associating GEF-1 (RA-GEF-1), is a Rap-specific guanine nucleotide exchange factor (GEF) that has a PSD-95/DlgA/ZO-1 (PDZ) domain, a RA domain and a region related to a cyclic nucleotide binding domain (RCBD). The RA domain of PDZ-GEF interacts with Rap1 and also contributes to the membrane localization of PDZ-GEF.

235-275 | 2.91e-03 | |||
General Receptor for Phosphoinositides-1-like Pleckstrin homology (PH) domain; GRP1/cytohesin3 and the related proteins ARNO (ARF nucleotide-binding site opener)/cytohesin-2 and cytohesin-1 are ARF exchange factors that contain a pleckstrin homology (PH) domain thought to target these proteins to cell membranes through binding polyphosphoinositides. The PH domains of all three proteins exhibit relatively high affinity for PtdIns(3,4,5)P3. Within the Grp1 family, diglycine (2G) and triglycine (3G) splice variants, differing only in the number of glycine residues in the PH domain, strongly influence the affinity and specificity for phosphoinositides. The 2G variants selectively bind PtdIns(3,4,5)P3 with high affinity,the 3G variants bind PtdIns(3,4,5)P3 with about 30-fold lower affinity and require the polybasic region for plasma membrane targeting. These ARF-GEFs share a common, tripartite structure consisting of an N-terminal coiled-coil domain, a central domain with homology to the yeast protein Sec7, a PH domain, and a C-terminal polybasic region. The Sec7 domain is autoinhibited by conserved elements proximal to the PH domain. GRP1 binds to the DNA binding domain of certain nuclear receptors (TRalpha, TRbeta, AR, ER, but not RXR), and can repress thyroid hormone receptor (TR)-mediated transactivation by decreasing TR-complex formation on thyroid hormone response elements. ARNO promotes sequential activation of Arf6, Cdc42 and Rac1 and insulin secretion. Cytohesin acts as a PI 3-kinase effector mediating biological responses including cell spreading and adhesion, chemotaxis, protein trafficking, and cytoskeletal rearrangements, only some of which appear to depend on their ability to activate ARFs. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.
