Proteomics (Proteome ID):UP000005640
Proteomics (Chromosome): Chromosome 4
Active Site:ACT_SITE 342 342 Proton donor/acceptor. {ECO:0000250|UniProtKB:P14384}.
Catalytic Activity: Reaction=Release of C-terminal arginine or lysine residues from polypeptides.; EC=3.4.17.10;
Cofactor:Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250|UniProtKB:P00730}; Note=Binds 1 zinc ion per subunit. {ECO:0000250|UniProtKB:P00730};
Function [CC]:Sorting receptor that directs prohormones to the regulated secretory pathway. Acts also as a prohormone processing enzyme in neuro/endocrine cells, removing dibasic residues from the C-terminal end of peptide hormone precursors after initial endoprotease cleavage. {ECO:0000250|UniProtKB:Q00493}.
Metal Binding:METAL 114 114 Zinc; catalytic. {ECO:0000250|UniProtKB:P00730}.; METAL 117 117 Zinc; catalytic. {ECO:0000250|UniProtKB:P00730}.; METAL 248 248 Zinc; catalytic. {ECO:0000250|UniProtKB:P00730}.
Tissue Specificity:Isoform 2, but not isoform 1, is overexpressed in hepatocellular carcinoma (at protein level), as well as in other tumors, including pheochromocytomas and paragangliomas. {ECO:0000269|PubMed:21285511}.
