Function
PCSK9 or Proprotein Convertase Subtilisin/Kexin type 9 is a proteinase which is part of cholesterol synthesis[1]. PCSK9 undergoes autocatalysis producing an active enzyme from its precursor. PCSK9 binds to EGF-A domain of the LDL receptor (LDLR) inducing its degradation.
Relevance
Low levels of LDL receptor are a cause of hypercholesterolemia since LDLR removes LDL cholesterol from the blood. Thus PCSK9 is an important drug target as its level affects the amount of cholesterol in blood[2].
