Function
function
Involved in the transfer of neutral lipids, including cholesteryl ester and triglyceride, among lipoprotein particles. Allows the net movement of cholesteryl ester from high density lipoproteins/HDL to triglyceride-rich very low density lipoproteins/VLDL, and the equimolar transport of triglyceride from VLDL to HDL.
Catalytic activity
- 1,2,3-tri-(9Z-octadecenoyl)-glycerol(in) = 1,2,3-tri-(9Z-octadecenoyl)-glycerol(out)
- cholesteryl (9Z,12Z)-octadecadienoate(in) = cholesteryl (9Z,12Z)-octadecadienoate(out)
- cholesteryl (9Z-octadecenoate)(in) = cholesteryl (9Z-octadecenoate)(out)
