CD36, also known as scavenger receptor B2 or fatty acid translocase, is a transmembrane glycoprotein that has roles in fatty acid uptake and lipid metabolism and signaling.1 It is composed of N- and C-terminal cytoplasmic tails, two transmembrane domains, and an extracellular loop that binds to a variety of lipid ligands, including long-chain fatty acids, oxidized LDL, and oxidized phospholipids, and protein ligands, such as thrombospondin (TSP-1), and is subject to post-translational modifications.1,2,3 CD36 is expressed by a variety of cells, including hematopoietic cells such as platelets, monocytes, and macrophages, as well as adipocytes, enterocytes, cardiac and skeletal myocytes, and endothelial and epithelial cells.1,4 It also exists as a soluble form, sCD36, which is produced via plasma proteases.2 CD36 expression is regulated by several transcription factors, including peroxisome proliferator-activated receptor (PPAR), STAT3, and hypoxia-inducible factor-1α (HIF-1α), in a tissue-dependent manner.3,1 It is localized to the plasma membrane and within endosomes, the endoplasmic reticulum, and mitochondria, and is translocated between these compartments in response to various stimuli, including insulin-induced PI3K signaling and muscle contraction-induced AMPK signaling, to regulate fatty acid uptake.2,3 It has additional roles in the phagocytosis of apoptotic cells and P. falciparum-infected red blood cells (RBCs), angiogenesis, thrombosis, inflammation, and atherosclerosis, as well as cancer metastasis.5,3 Cayman’s Scavenger Receptor B2/CD36 Extracellular Domain (mouse, recombinant) protein can be used for binding assays. This protein consists of 421 amino acids and has a calculated molecular weight of 47.8 kDa. By SDS-PAGE, under reducing conditions, the apparent molecular mass of the protein is 80-90 kDa due to glycosylation.WARNING This product is not for human or veterinary use.
