Proprotein convertase 1 (PC1) is an enzyme that is responsible for splitting off unnecessary protein components of many proteohormones and neuropeptides (the so-called post - translational modification ). For example, PC1 (together with PC 2 ) is necessary to produce insulin from proinsulin . PC1 is a serine protease found in many vertebrates . Mutations in the human PCSK1 - gene can lead to deficiency PC1 very rare, which is accompanied by severe metabolic disorders.
Substrates for PC1 include proinsulin, proopiomelanocortin , prorenin , proenkephalin , prodynorphin , prosomatostatin and oxytocin - neurophysin .
