Protein Domain
Type: Family
Description: Small GTPases form an independent superfamily within the larger class of regulatory GTP hydrolases. This superfamily contains proteins that control a vast number of important processes and possess a common, structurally preserved GTP-binding domain [, ]. Sequence comparisons of small G proteins from various species have revealed that they are conserved in primary structures at the level of 30-55% similarity [].Crystallographic analysis of various small G proteins revealed the presence of a 20kDa catalytic domain that is unique for the whole superfamily [, ]. The domain is built of five alpha helices (A1-A5),six β-strands (B1-B6) and five polypeptide loops (G1-G5). A structural comparison of the GTP- and GDP-bound form, allows one to distinguish two functional loop regions: switch I and switch II that surround the gamma-phosphate group of the nucleotide. The G1 loop (also called the P-loop) that connects the B1 strand and the A1 helix is responsible for the binding of the phosphate groups. The G3 loop provides residues for Mg2 and phosphate binding and is located at the N terminus of the A2 helix. The G1 and G3 loops are sequentially similar to Walker A and Walker B boxes that are found in other nucleotide binding motifs. The G2 loop connects the A1 helix and the B2 strand and contains a conserved Thr residue responsible for Mg2 binding. The guanine base is recognised by the G4 and G5 loops. The consensus sequence NKXD of the G4 loop contains Lys and Asp residues directly interacting with the nucleotide. Part of the G5 loop located between B6 and A5 acts as a recognition site for the guanine base [].The small GTPase superfamily can be divided into at least 8 different families, including:Arf small GTPases. GTP-binding proteins involved in protein trafficking by modulating vesicle budding and uncoating within the Golgi apparatus.Ran small GTPases. GTP-binding proteins involved in nucleocytoplasmic transport. Required for the import of proteins into the nucleus and also for RNA export.Rab small GTPases. GTP-binding proteins involved in vesicular traffic.Rho small GTPases. GTP-binding proteins that control cytoskeleton reorganisation.Ras small GTPases. GTP-binding proteins involved in signalling pathways.Sar1 small GTPases. Small GTPase component of the coat protein complex II (COPII) which promotes the formation of transport vesicles from the endoplasmic reticulum (ER).Mitochondrial Rho (Miro). Small GTPase domain found in mitochondrial proteins involved in mitochondrial trafficking.Roc small GTPases domain. Small GTPase domain always found associated with the COR domain.This entry represents the Rho subfamily of Ras-like small GTPases. The small GTPase-like protein LIP2 (light insensitive period 2) from Arabidopsis thalianais implicated in control of the plant circadian rhythm []. The crystal structures of a number of the members of this entry have been determined: Rnd3/RhoE [], RhoA []and Cdc42 [].
Protein Domain
Type: Domain
Description: The Rho family GTPases Rho, Rac and CDC42 regulate a diverse array of cellular processes. Like all members of the Ras superfamily, the Rho proteins cycle between active GTP-bound and inactive GDP-bound conformational states.Activation of Rho proteins through release of bound GDP and subsequentbinding of GTP, is catalysed by guanine nucleotide exchange factors (GEFs) inthe Dbl family. The proteins encoded by members of the Dbl family share acommon domain, presented in this entry, of about 200 residues (designated the Dbl homology or DH domain) that has been shown to encode a GEF activity specific for a number of Rho family members. In addition, all family members possess a second, shared domain designated the pleckstrin homology (PH) domain (). Trio and its homologue UNC-73 are unique within the Dbl family insomuch as they encode two distinct DH/PH domain modules. The PH domain is invariably located immediately C-terminal to the DH domain and this invariant topography suggests a functional interdependence between these two structural modules. Biochemical data have established the role of the conserved DH domain in Rho GTPase interaction and activation, and the role of the tandem PH domain in intracellular targeting and/or regulation of DH domain function. The DH domain of Dbl has been shown to mediate oligomerisation that is mostly homophilic in nature. In addition to the tandem DH/PH domains Dbl family GEFs contain diverse structural motifs like serine/threonine kinase, RBD, PDZ, RGS, IQ, REM, Cdc25, RasGEF, CH, SH2, SH3, EF, spectrin or Ig.The DH domain is composed of three structurally conserved regions separated bymore variable regions. It does not share significant sequence homology withother subtypes of small G-protein GEF motifs such as the Cdc25 domain and theSec7 domain, which specifically interact with Ras and ARF family small GTPases, respectively, nor with other Rho protein interactive motifs, indicating that the Dbl family proteins are evolutionarily unique. The DH domain is composed of 11 alpha helices that are folded into a flattened, elongated α-helix bundle in which two of the three conserved regions, conserved region 1 (CR1) and conserved region 3 (CR3), are exposed near the centre of one surface. CR1 and CR3, together with a part of alpha-6 and the DH/PH junction site, constitute the Rho GTPase interacting pocket.
Protein Domain
Type: Domain
Description: This entry represents the N-terminal PH domain of FGD1.In general, FGDs (including FGD1, FGD2, FGD3 and FGD4/Frabin) have a RhoGEF (DH) domain, followed by an N-terminal PH domain, a FYVE domain and a C-terminal PH domain. All FGDs are guanine nucleotide exchange factors that activates the Rho GTPase Cdc42, an important regulator of membrane trafficking. The RhoGEF domain is responsible for GEF catalytic activity, while the N-terminal PH domain is involved in intracellular targeting of the DH domain []. Mutations in the FGD1 gene are responsible for the X-linked disorder known as faciogenital dysplasia (FGDY) []. Both FGD1 and FGD3 are targeted by the ubiquitin ligase SCF(FWD1/beta-TrCP) upon phosphorylation of two serine residues in its DSGIDS motif and subsequently degraded by the proteasome. However, FGD1 and FGD3 induced significantly different morphological changes in HeLa Tet-Off cells and while FGD1 induced long finger-like protrusions, FGD3 induced broad sheet-like protrusions when the level of GTP-bound Cdc42 was significantly increased by the inducible expression of FGD3. They also reciprocally regulated cell motility in inducibly expressed in HeLa Tet-Off cells, FGD1 stimulated cell migration while FGD3 inhibited it. FGD1 and FGD3 therefore play different roles to regulate cellular functions, even though their intracellular levels are tightly controlled by the same destruction pathway through SCF(FWD1/beta-TrCP) [, ].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 [].
