Proprotein Convertase 1/3 Antibody

Proprotein Convertase, Subtilisin/Kexin-Type, 1, also known as PC1 or NEC1, is an enzyme that in humans is encoded by the PCSK1 gene. It is a neuroendocrine convertase that belongs to a family of subtilisin-like serine endoproteases that process large precursor proteins into mature bioactive products. By in situ hybridization, Seidah et al. (1991) mapped the gene to human chromosome 5q15-q21 and mouse chromosome 13. Ohagi et al. (1996) noted that PCSK1 initiates the sequential processing of proinsulin to insulin by cleaving the proinsulin molecule on the C-terminal side of the dibasic peptide, arg31-arg32, joining the B-chain and C-peptide. By observing the phenotypic features in patients with PCSK1 mutations, Jackson et al. (2003) concluded that human intestinal absorptive function is dependent on the enzymes activity.
