SpeciesHomo sapiens (NCBI taxonomy ID: 9606)
GON/A
Domain Architecture (Details)
InterPro domains unassigned to SynO:
SH3 (Src homology 3) domains are often indicative of a protein involved in signal transduction related to cytoskeletal organisation. These were first described in the Src cytoplasmic tyrosine kinase . The structure is a partly opened beta barrel.
  IPR011511:Variant SH3
SH3 (src Homology-3) domains are small protein modules containing approximately 50 amino acid residues . They are found in a great variety of intracellular or membrane-associated proteins for example.n a variety of proteins with enzymatic activity.n adaptor proteins that lack catalytic sequences and in cytoskeletal proteins.uch as fodrin and yeast actin binding protein ABP-1. The SH3 domain has a characteristic fold which consists of five or six beta-strands arranged as two tightly packed anti-parallel beta sheets. The linker regions may contain short helices . The surface of the SH2-domain bears a flat.ydrophobic ligand-binding pocket which consists of three shallow grooves defined by conservative aromatic residues in which the ligand adopts an extended left-handed helical arrangement. The ligand binds with low affinity but this may be enhanced by multiple interactions.The region bound by the SH3 domain is in all cases proline-rich and contains PXXP as a core-conserved binding motif. The function of the SH3 domain is not well understood but they may mediate many diverse processes such as increasing local concentration of proteins.ltering their subcellular location and mediating the assembly of large multiprotein complexes .
  IPR001452:Src homology-3
The tetratrico peptide repeat (TPR) is a structural motif present in a wide range of proteins . It mediates proteinprotein interactions and the assembly of multiprotein complexes . The TPR motif consists of 316 tandem-repeats of 34 amino acids residues.lthough individual TPR motifs can be dispersed in the protein sequence. Sequence alignment of the TPR domains reveals a consensus sequence defined by a pattern of small and large amino acids. TPR motifs have been identified in various different organisms.anging from bacteria to humans. Proteins containing TPRs are involved in a variety of biological processes.uch as cell cycle regulation.ranscriptional control.itochondrial and peroxisomal protein transport.eurogenesis and protein folding. The X-ray structure of a domain containing three TPRs from protein phosphatase 5 revealed that TPR adopts a helixturnhelix arrangement.ith adjacent TPR motifs packing in a parallel fashion.esulting in a spiral of repeating anti-parallel alpha-helices . The two helices are denoted helix A and helix B. The packing angle between helix A and helix B is ~24° within a single TPR and generates a right-handed superhelical shape. Helix A interacts with helix B and with helix A of the next TPR. Two protein surfaces are generated: the inner concave surface is contributed to mainly by residue on helices A.nd the other surface presents residues from both helices A and B.
  IPR001440:Tetratricopeptide TPR_1
Protein prenyltransferases catalyze the transfer of the carbon moiety of C15 farnesyl pyrophosphate or geranylgeranyl pyrophosphate synthase to a conserved cysteine residue in a CaaX motif of protein and peptide substrates. The addition of a farnesyl group is required to anchor proteins to the cell membrane. In the 3D structure of a mammalian Ras farnesyltransferases (Ftase).oth subunits are largely composed of alpha-helices. The alpha-2 to alpha-15 helices in the alpha subunit fold into a novel helical hairpin structure.esulting in a crescent-shape domain that envelopes part of the subunit. The 12 helices of the beta-subunit form an alpha-alpha barrel. Six additional helices connect the inner core of helices and form the outside of the helical barrel. A deep cleft surrounded by hydrophobic amino acids in the centre of the barrel is proposed as the FPP-binding pocket. A single Zn2+ ion is located at the junction between the hydrophilic surface groove near the subunit interface. The SSF signature in this entry is currently under review. Please be aware that some of the protein hits may be false positives.
  IPR008940:Protein prenyltransferase
This domain consists of a multi-helical fold comprised of two curved layers of alpha helices arranged in a regular right-handed superhelix.here the repeats that make up this structure are arranged about a common axis . These superhelical structures present an extensive solvent-accessible surface that is well suited to binding large substrates such as proteins and nucleic acids. This topology has been found with a number of repeats and domains.ncluding the tetratricopeptide repeat (TPR) (found in kinesin light chains.NAP regulatory proteins.lathrin heavy chains and bacterial aspartyl-phosphate phosphatases).nd the pentatricopeptide repeat (PPR) (RNA-processing proteins). The TRP is likely to be an ancient repeat.ince it is found in eukaryotes.acteria and archaea.hereas the PPR repeat is found predominantly in higher plants. The superhelix formed from these repeats can bind ligands at a number of different regions.nd has the ability to acquire multiple functional roles .
