Background: CD38

CD38, also known as ADP-ribosyl cyclase, converts NAD(P)+ into three separate products with calcium mobilizing ability: cyclic ADP-ribose, NAADP+, and ADP-ribose (1). CD38 is a Type II transmembrane glycoprotein composed of an intracellular domain, a single transmembrane helix domain, and a large extracellular domain that contains the catalytic site (2). CD38 is expressed in B and T lymphocytes, osteoclasts, and in cardiac, pancreatic, liver and kidney cells (3,4). Through its production of cyclic ADP-ribose, CD38 modulates calcium-mediated signal transduction in many types of cells (5,6). CD38 is also reported to bind as a receptor to trigger signaling cascades (7,8). Through both mechanisms, CD38 influences proliferation and trafficking (8,9). CD38 is used as a marker for poor prognosis in chronic lymphocytic leukemia and multiple myeloma and is an attractive cancer immunotherapy drug target (8-11).
