Proprotein convertase 1, also known as prohormone convertase, prohormone convertase 3, or neuroendocrine convertase 1 and often abbreviated as PC1/3 is an
Function
PC1/3 is an enzyme that performs the
Proprotein convertase 1 is the enzyme largely responsible for the first step in the biosynthesis of insulin. Following the action of proprotein convertase 1, a carboxypeptidase is required to remove the basic residues from the processing intermediate and generate the bioactive form of insulin. Another prohormone convertase, proprotein convertase 2 plays a more minor role in the first step of insulin biosynthesis, but a greater role in the first step of glucagon biosynthesis. The knockout of proprotein convertase 1 is not lethal in mice or humans, most likely due to the presence of the second convertase, although mice lacking proprotein convertase 1 activity show a number of defects including slow growth.[citation needed]
Proprotein convertase 1 is a calcium (Ca2+) activated
Proprotein convertase 1 converts prorenin into renin.[7]
Clinical significance
Variants in the PCSK1 gene may be associated with obesity.[8]
