NAD+ and cADPR Signaling

Nicotinamide adenine dinucleotide (NAD+) and its metabolites are ideally suited to their role in cell signaling pathways because of their universal presence throughout many metabolic pathways. The NAD+ metabolites ADP-ribose and cyclic ADP-ribose (cADPR) act as key second messengers in Ca2+ signaling. ADP-ribose activates cation influx and cADPR modulates calcium release in many biological systems. The NAD+ phosphate metabolite ß-NAADP is a potent stimulator of intracellular Ca2+ mobilization in a variety of cell types.

The universal prevalence of NAD+ / protein interactions can be utilized in the development of cellular assays. One such example is shown below and incorporates the use of the NAD dependent ADP-ribosylation posttranslational protein modification to label cell surface proteins for detection (Krebs C et al. (2003)).
