CD63 is a protein encoded by the CD63 gene which is approximately 25, 6 kDa. CD63 is localised to the cell membrane. It is involved in response to elevated platelet cytosolic Ca2+, the innate immune system and adhesion. This protein falls under the tetraspanin family. Most of these members are characterized by the presence of four hydrophobic domains. It is a cell surface glycoprotein that is known to complex with integrins and may function as a blood platelet activation marker. It also mediates signal transduction events that play a role in the regulation of cell development, activation, growth and motility. CD63 is expressed in skin, lung, blood, liver and muscle. Mutations in the CD63 gene may result in mast cell disease. STJ96890 was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen. This polyclonal antibody detects endogenous levels of CD63 protein.
