General description

CD38 is a 45 kDa type II integral membrane glycoprotein consisting of an N-terminal 20 amino acid cytoplasmic domain, a 23 amino acid transmembrane domain, and a 257 amino acid extracellular domain. CD38 is associated with different molecules in different cell types and these unique combinations cause unique cell-type specific signaling. One of the known ligands that activates CD38-mediated signaling is CD31 (Deaglio, 2001). CD38 is expressed by a number of different cell types and the pattern of expression often changes with differentiation and maturation. Thus, CD38 expression is found during early stages of B and T-cell differentiation, is lacking during the later intermediate stages, and is regained near the end of maturation. CD38 is expressed at variable levels on the majority of hematopoietic cells, prevalently during early differentiation and activation, and it is expressed strongly on plasma cells (Jackson, 1990; Terstappen, 1990; Morra, 1997). CD38-postive cell types outside the hematopoietic system include subsets from the gut, brain, prostate, pancreas, bone, eye, and muscle (Deaglio, 2001). CD38 is expressed on approximately 60% of CD34-positive peripheral blood mononuclear cells. The least mature CD34-postive cells are characterized by a lack of CD38 (Herbein, 1994).
Anti-CD38, AT13/5 was included in the Sixth International Workshop and Conference on Human Leucocyte Differentiation Antigens, and studies by a number of laboratories confirmed its reactivity with CD38 (Morra, 1997).
