Comments
  • FUNCTION: Involved in the processing of hormone and other protein precursors at sites comprised of pairs of basic amino acid residues. Substrates include POMC, renin, enkephalin, dynorphin, somatostatin and insulin.
  • CATALYTIC ACTIVITY: Release of protein hormones, neuropeptides and renin from their precursors, generally by hydrolysis of -Lys-Arg-|- bonds.
  • COFACTOR: Calcium.
  • SUBCELLULAR LOCATION: Cytoplasmic vesicle, secretory vesicle. Note=Localized in the secretion granules.
  • DISEASE: Defects in PCSK1 are the cause of proprotein convertase 1 deficiency (PC1 deficiency) [MIM:600955]. PC1 deficiency is characterized by obesity, hypogonadism, hypoadrenalism, reactive hypoglycemia as well as marked small-intestinal absorptive dysfunction It is due to impaired processing of prohormones.
  • SIMILARITY: Belongs to the peptidase S8 family. Furin subfamily [view classification].
