APOA2

Apolipoprotein A-II is a protein that in humans is encoded by the "APOA2" gene.
Function.
This gene encodes apolipoprotein (apo-) A-II, which is the second most abundant protein of the high density lipoprotein particles. The protein is found in plasma as a monomer, homodimer, or heterodimer with apolipoprotein D. Defects in this gene may result in apolipoprotein A-II deficiency or hypercholesterolemia.
Interactions.
APOA2 has been shown to interact with PLTP.
