CD36, Human, mAb FA6-152, biotinylated
Monoclonal antibody FA6-152 recognizes human CD36 (88-kDa), a cell surface class B scavenger
receptor, also known as thrombospondin receptor CD36 is a heavily N-glycosylated transmembrane
protein of ~88 kDa with two short intracellular domains and a large extracellular domain. The protein is
sensitive for neuroaminidase, resulting in a shift from 88 to 85 kDa. CD36 is expressed on platelets,
mature monocytes and macrophages, microvascular endothelial cells, mammary endothelial cells,
during stages of erythroid cell development and on some macrophage derived dendritic cells. The
antibody recognizes adult and fetal monocytes, platelets and reticulocytes, but doesn’t stain
lymphocytes and granulocytes. Reactivity has also been found in small intestine, kidney, liver and
thyroid. CD36 expression is primarily controlled by the transcription heterodimer PPARg-RXR
(peroxisome proliferator-activated receptor-g-retinoid-X-receptor). CD36 is preferentially found within
lipid rafts, which facilitates its association with receptors, signaling and adaptor molecules. It is a
receptor and transporter of oxidized lipids and long chain fatty acids. CD36 has been implicated in
many biological processes including angiogenesis, phagocytosis, inflammation, and lipid and glucose
metabolism. Several in vivo models support the role of the thrombospondin / CD36 system in
angiogenesis and tumor growth. An important role for CD36 has been found in Malaria as major
receptor for P. falciparum-infected red blood cells. CD36 is associated with Src-family kinases and
with the integrins α3β1 and α6β1. Recently, CD36 has been identified as a protein that is required for
toll like receptor (TLR2) recognition of di-acylated bacterial lipopeptides and lipoteichoic acid4.
Furthermore, CD36 has been shown to function as phagocytic receptor for apoptotic cells. Many
different ligands have been reported to interact with CD36, suggesting that CD36 could recognize a
structure-based domain rather than specific contact residues. Monoclonal antibody FA6-152 blocks
the biological activity of CD36 by blocking collagen/thrombospondin binding. The antibody
agglutinates fetal but not adult erythrocytes.
