  • proprotein convertase subtilisin/kexin type 9
  • PCSK9
  • neural apoptosis-regulated convertase 1
  • subtilisin/kexin-like protease PC9
  • proprotein convertase 9

General information

  • PCSK9 is the ninth member of a family of secretory serine proteinases known as the proprotein convertases. [1]
  • It induces an enhanced cellular degradation of the low density lipoprotein receptor (LDLR) in endosomes-lysosomes. [2]
  • PCSK9 binds to a ∼33-kDa protein identified as annexin A2 (AnxA2) but not to the closely related annexin A1. [3]
