Summary
The prohormone convertases (PC) 1/3 and 2 are calcium-activated eukaryotic subtilisins with low pH optima which accomplish the limited proteolysis of peptide hormone precursors within neurons and endocrine cells. We review the biochemistry, regulation, and roles of PC1/3 and 2 in disease, with an emphasis on the work published in the last 10 years. In the 20 years since their discovery, a great deal has been learned about their localization and cellular functions. Both PCs share the same four domains: the propeptides perform important roles in controlling activation and targeting; the catalytic domains confer specificity, with PC1/3 possessing a more restricted binding pocket than that of PC2; the P domain is required for expression and contributes to enzymatic properties; and the C-terminal tail assists in proper routing to granules. PC1/3, but not PC2, exists in full-length and C-terminally truncated forms that exhibit different biochemical properties. Both enzymes associate with binding proteins; proSAAS is thought to modulate precursor cleavage by PC1/3, while co-expression of 7B2 is obligatory for the formation of active PC2. New studies have revealed an increasingly important role for PC1/3 polymorphisms and mutations in glucose homeostasis and obesity
