InterPro : IPR002884

Name  Proprotein convertase, P Short Name  PrprotnconvertsP
Type  Domain Description  This domain, termed the P domain is approximately 150 amino acids in length and C-terminal to a serine endopeptidase domain which belong to MEROPS peptidase family S8 (clan SB), subfamily S8B (kexin). The domain is primarily associated with the calcium-dependent serine endopeptidases, kex2/subtilisin proprotein convertases (PCs), which have been identified in all eukaryotes []and in the gammaproteobacteria, Nostoc (cyanobacteria) and in Streptomyces avermitilis.The P domain appears necessary for folding and maintaining the endopeptidase catalytic domain and to regulate its calcium and acidic pH dependence. In addition, contained within the middle of the P domain in most PC family members is the cognate integrin binding RGD sequence [], which may be required for intracellular compartmentalization and maintenance of enzyme stability within the ER. The integrity of the RGD sequence of proprotein convertase PC1 is critical for its zymogen and C-terminal processing and for its cellular trafficking [, ]. The carboxy-terminal tail provides uniqueness to each PC family member being the least conserved region of all convertases [].
