Abstract

Biologically active peptides, such as peptide hormones, neuropeptides and growth factors, are known to be synthesized as larger precursor proteins and converted to active peptides by proteolytic cleavage at the carboxyl side of paired basic amino acids1,2,3. This process is found also in the activation of membrane-bound receptor proteins such as insulin receptor and many secreted proteins like serum albumin. Kexin family proteases were identified as processing proteases for these proteins; they share a subtilisin-like catalytic domain and require calcium ion for their activities2,3. Kexin family proteases are widely distributed in nature, from yeast, to mammals4,5,6. Currently seven mammalian kexins have been reported: furin4, PCI/37, PC2,8 PACE45,6, PC49, PC5/610, and PC7 11.
