The CD63 antigen (Melanoma 1 antigen) is a glycoprotein of 40-60kD belonging to the tetraspans family (TM4SF). CD63 is intracellular lysosomal/endosomal/granule protein that is translocated to cell surface upon activation of platelets, endothelial cells, and granulocytes (activation marker). CD63 is also expressed on monocytes/macrophages and endothelium. Its cellular function has not been exactly elucidated. CD63 is thought to be associated with the early stages of melanoma tumor progression (in regulation of motility and adhesion of melanoma cells).
