Background: CD63

CD63 (cluster of differentiation 63), also known as lysosome associated membrane protein 3 (LAMP-3), is a membrane spanning glycoprotein with a molecular mass ranging from 30-60 kDa that was the first characterized member of the tetraspanin superfamily (1,2). CD63 is ubiquitously expressed and largely present on the cell surface in the endosomal system (1-3). More specifically, it is generally present in multivesicular bodies (MVBs), also called late endosomes, and lysosomes (1). The CD63 molecule is a total of 238 amino acids (aa), has four hydrophobic membrane-spanning regions and three N-glycosylation sites, and the encoded protein has a theoretical molecular weight of 25 kDa (2,3). CD63 both directly and indirectly interacts with other proteins including integrins, cell surface receptors, other tetraspanins, kinases, and adapter proteins, to name a few (1). CD63 is involved in many cell processes including cell survival and activation, cell adhesion, invasion, and migration (1). Additionally, CD63 has been shown to interact with tissue inhibitor of metalloproteinase 1 (TIMP-1), which originally thought to be an inhibitor of cancer progression has recently been shown to have cancer promoting properties as well (1,4). The CD63-TIMP-1 interaction has been shown to activate the PI3K/AKT pathway in lung adenocarcinoma cells and also promote survival and invasion of acute myeloid leukemia cells (1).CD63 is a useful flow cytometry marker for basophil granulocytes and can be used for the basophil activation test (BAT) to assess IgE-mediated allergy response (5). As CD63 was initially discovered on activated blood platelets and is a lysosomal-associated protein it makes sense it would be involved in platelet or lysosomal-related disorders (1,2). More precisely, CD63 is associated with Hermansky-Pudlak syndrome, a disease characterized by albinism and platelet storage pool deficiency (6).
