Protein Structure
UniProt Annotation
Function Cleaves substrates with C-terminal arginine residues. Probably modulates the Wnt signaling pathway, by cleaving some undefined protein. May play a role in cleavage during prohormone processing. {ECO:0000269PubMed:11766880, ECO:0000269PubMed:12417617, ECO:0000269PubMed:9099699}.
Subcellular Localization Secreted, extracellular space, extracellular matrix {ECO:0000269PubMed:10671522}.
Disease Associations
Tissue Specificity In placenta, it is present within invasive trophoblasts and in the surrounding extracellular space. Also present in amnion cells, but is not readily apparent in the extracellular matrix of this cell type. Present in normal pituitary gland and neoplastic pituitary gland (especially POMC-, GH- and PRL-producing adenomas) (at protein level). Widely expressed. {ECO:0000269PubMed:10671522, ECO:0000269PubMed:12417617, ECO:0000269PubMed:9099699}.
