Target Background

(From Uniprot)
Synthesizes the second messengers cyclic ADP-ribose and nicotinate-adenine dinucleotide phosphate, the former a second messenger for glucose-induced insulin secretion. Also has cADPr hydrolase activity. Also moonlights as a receptor in cells of the immune system.

  1. CD38 and cADPR are key players in the orches- tration of cellular responses to respiratory syncytial virus by infected monocyte-derived dendritic cells. PMID: 29178427
