[http://en.wikipedia.org/wiki/Cholesterylester_transfer_protein Cholesteryl ester transfer protein (CETP)] belongs to a family of proteins that engages lipid transfer. CETP is a hydrophobic glycoprotein which is mainly synthesized in the liver, but also in the intestine, spleen and adrenal glands.
[http://en.wikipedia.org/wiki/Cholesterylester_transfer_protein Cholesteryl ester transfer protein (CETP)] belongs to a family of proteins that engages lipid transfer. The [http://en.wikipedia.org/wiki/Homo_sapiens Human] CETP is a hydrophobic glycoprotein which is mainly synthesized in the liver, but also in the intestine, spleen and adrenal glands. The gene coding for CETP is located on the sixteen chromosome (16q21).
In the plasma, CETP is implicated in the transport of cholesteryl esters from the atheroprotective high-density lipoproteins (HDL) to the atherogenic lower-density lipoproteins (LDL). CETP also mediates the transport of triglycerides from LDL to HDL.  
In the plasma, CETP is implicated in the transport of cholesteryl esters from the atheroprotective high-density lipoproteins (HDL) to the atherogenic lower-density lipoproteins (LDL) and also mediates the transport of triglycerides from LDL to HDL. Most of the time, CETP facilites homoexchange by exchanging a triglyceride for a triglyceride and a cholesteryl ester for a cholesteryl ester between lipoproteins. However CETP can also promotes heteroexchange.
The cristal structure of the [http://en.wikipedia.org/wiki/Homo_sapiens Human] CETP, in complex with four bound lipid molecules at 2,1 Å resolution shows a long tunnel traversing the core of the molecule. This tunnel has two large openings allowing lipids access.
