Serine endoprotease that processes various proproteins by cleavage at paired basic amino acids, recognizing the RXXX[KR]R consensus motif. Likely functions in the constitutive secretory pathway.
Subcellular locations: Golgi apparatus, Trans-Golgi network membrane
Seems to be localized intracellularly to the trans Golgi network.
Expressed in spleen, thymus, prostate, testis, ovary, small intestine, colon and peripheral blood leukocyte.
