Proprotein convertase 2

Proprotein convertase 2 (PC2) is a serine protease and proprotein convertase It is also referred to as "prohormone convertase 2". PC2, like proprotein convertase 1 (PC1), is an enzyme responsible for the maturation of many neuroendocrine peptides from their precursors, such as the conversion of proinsulin to insulin. PC2 plays only a minor role in insulin biosynthesis, but a greater role in glucagon biosynthesis compared to PC1.
