CD36(redirected from Glycoprotein IIIb)
a transmembrane protein present on monocytes, platelets, megakaryocytes, the umbilical vein, small-vessel endothelium, reticulocytes, and mammary epithelium that may be involved in signal transduction; expressed in myeloproliferative disorders.
CD36A gene on chromosome 7q11.2 that encodes the fourth major platelet surface glycoprotein, which is a receptor for thrombospondin. It is acts as a cell adhesion molecule, binding to collagen, thrombospondin, anionic phospholipids, oxidised LDL, long-chain fatty acids and Plasmodium falciparum-parasitised erythrocytes.
Defects in CD36 cause platelet glycoprotein deficiency; genetic variations in CD36 are associated with susceptibility to coronary heart disease type 7.
