Domain Architecture (Details)
InterPro domains unassigned to SynO:
Insulin receptor substrate-1 proteins contain both a pleckstrin homology domain and a phosphotyrosine binding (PTB) domain. These domains facilitate interaction with the activated tyrosine-phosphorylated insulin receptor. The PTB domain is situated towards the N terminus. Two arginines in this domain are responsible for hydrogen bonding phosphotyrosine residues on a Ac-LYASSNPApY-NH2 peptide in the juxtamembrane region of the insulin receptor. Further interactions via bridged water molecules are coordinated by residues an Asn and a Ser residue . The PTB domain has a compact.-stranded beta-sandwich structure.apped by a C-terminal helix. The substrate peptide fits into an L-shaped surface cleft formed from the C-terminal helix and strands 5 and 6 .

The pleckstrin homology (PH) domain is a domain of about 100 residues that occurs in a wide range of proteins involved in intracellular signaling or as constituents of the cytoskeleton .The function of this domain is not clear.everal putative functions have been suggested:binding to the beta/gamma subunit of heterotrimeric G proteins.inding to lipids..g. phosphatidylinositol-4.-bisphosphate.inding to phosphorylated Ser/Thr residues.ttachment to membranes by an unknown mechanism.It is possible that different PH domains have totally different ligand requirements.The 3D structure of several PH domains has been determined . All known cases have a common structure consisting of two perpendicular anti-parallel beta sheets.ollowed by a C-terminal amphipathic helix. The loops connecting the beta-strands differ greatly in length.aking the PH domain relatively difficult to detect. There are no totally invariant residues within the PH domain.Proteins reported to contain one more PH domains belong to the following families:Pleckstrin.he protein where this domain was first detected.s the major substrate of protein kinase C in platelets. Pleckstrin is one of the rare proteins to contains two PH domains.Ser/Thr protein kinases such as the Akt/Rac family.he beta-adrenergic receptor kinases.he mu isoform of PKC and the trypanosomal NrkA family.Tyrosine protein kinases belonging to the Btk/Itk/Tec subfamily.Insulin Receptor Substrate 1 (IRS-1).Regulators of small G-proteins like guanine nucleotide releasing factor GNRP (Ras-GRF) (which contains 2 PH domains).uanine nucleotide exchange proteins like vav.bl.oS and Saccharomyces cerevisiae CDC24.TPase activating proteins like rasGAP and BEM2/IPL2.nd the human break point cluster protein bcr.Cytoskeletal proteins such as dynamin (see ).aenorhabditis elegans kinesin-like protein unc-104 (see ).pectrin beta-chain.yntrophin (2 PH domains) and S. cerevisiae nuclear migration protein NUM1.Mammalian phosphatidylinositol-specific phospholipase C (PI-PLC) (see ) isoforms gamma and delta. Isoform gamma contains two PH domains.he second one is split into two parts separated by about 400 residues.Oxysterol binding proteins OSBP.. cerevisiae OSH1 and YHR073w.Mouse protein citron. putative rho/rac effector that binds to the GTP-bound forms of rho and rac.Several S. cerevisiae proteins involved in cell cycle regulation and bud formation like BEM2.EM3.UD4 and the BEM1-binding proteins BOI2 (BEB1) and BOI1 (BOB1).C. elegans protein MIG-10.C. elegans hypothetical proteins C04D8.1.06H7.4 and ZK632.12.S. cerevisiae hypothetical proteins YBR129c and YHR155w.

Pleckstrin homology (PH) domains are small modular domains that occur once.r occasionally several times.n a large variety of signalling proteins.here they serve as simple targeting domains that recognize only phosphoinositide headgroups . PH domains can target their host protein to the plasma and internal membranes through its association with phosphoinositides. PH domains have a partly opened beta-barrel topology that is capped by an alpha helix. Proteins containing PH domains include pleckstrin (N-terminal).hospholipase C delta-1.eta-spectrin.ynamin.on-of-sevenless.rp1.nc-89.app1 and Rac-alpha kinase.The structure of PH domains is similar to the phosphotyrosine-binding domain (PTB) found in IRS-1 (insulin receptor substrate 1).hc adaptor and Numb; to the Ran-binding domain.ound in Nup nuclear pore complex and Ranbp1; to the Enabled/VASP homology domain 1 (EVH1 domain).ound in Enabled.ASP (vasodilator-stimulated phosphoprotein).omer and WASP actin regulatory protein; to the third domain of FERM.ound in moesin.adixin.zrin.erlin and talin; and to the PH-like domain of neurobeachin.
