Determination of ADP-Ribosyl Cyclase Activity, Cyclic ADP-Ribose, and Nicotinic Acid Adenine Dinucleotide Phosphate in Tissue Extracts
Time of Update: 2021-03-12
Cyclic ADP-ribose (cADPR) is a novel second messenger that releases calcium from intracellular stores.
Although first shown to release calcium in the sea urchin egg, cADPR has been shown since to be active in a variety of cells and tissues, from plant to human.
