| Bioactivity | Cyclic ADP-ribose ammonium (cADPR ammonium) is a potent second messenger for calcium mobilization that is synthesized from NAD+ by an ADP-ribosyl cyclase. Cyclic ADP-ribose ammonium increases cytosolic calcium mainly by Ryanodine receptor-mediated release from endoplasmic reticulum and also by extracellular influx through the opening of TRPM2 channels[1][2][3]. |
| Invitro | cADPR (20 nM) elicits a large rapid Ca2+ release in sea urchin eggs homogenates[1].cADPR (100 µM; 10 min) induces a sustained elevation of intracellular calcium concentration in a subset (64%) of cultured astrocytes[4].cADPR (100 µM) and heat (35-38.5 ℃) stimulates oxytocin OT release from the isolated hypothalami of male mice in culture[5]. |
