A family of plasma proteins (lipid transfer proteins, LTPII, 476 aa) that bind phospholipids and facilitate their transfer between cellular membranes. They have homology with cholesteryl ester transfer protein (lipid transfer protein I). Phosphatidylinositol transfer protein (PIPTP, 271 aa) is specific for PI. Glycolipid transfer protein is a soluble protein (209 aa) that selectively accelerates the transfer of glycosphingolipids and glycoglycerolipids between donor and acceptor membranes.
