Cluster of Differentiation CD38

Function

Cluster of Differentiation 38 (CD38), known also as ADP-ribosyl cyclase 1 (ADPRC1), catalyzes the synthesis and hydrolysis of cyclic ADP-ribose from NAD+ to ADP-ribose (ADPR). It is found on the surface of immune cells. It also functions in cell adhesion, signal transduction and Ca+2 signaling. ADP-ribosyl cyclase (ADPRC) is the Aplysia californica homolog of CD38. It catalyzes the synthesis and hydrolysis of cyclic ADP-ribose. It uses NAD+ as substrate and produces cyclic ADP-ribose (cADPR).^[1]

Relevance

CD38 is used as a marker for cell activation and for leukemia.

Structural highlights

CD38 active site contains NAD.
