  • 17303
Name Apolipoprotein C-II
Synonyms
  1. Apo-CII
  2. ApoC-II
  3. Apolipoprotein C2
Gene Name APOC2
Protein Type Unknown
Biological Properties
General Function Involved in enzyme activator activity
Specific Function Component of the very low density lipoprotein (VLDL) fraction in plasma, and is an activator of several triacylglycerol lipases. The association of APOC2 with plasma chylomicrons, VLDL, and HDL is reversible, a function of the secretion and catabolism of triglyceride-rich lipoproteins, and changes rapidly
