International research collaborators have identified a new family of proteins, TPC2 (two-pore channels), that facilitates calcium signaling from specialized subcellular organelles. The study, to be published April 22 in Nature, is the first to isolate TPC2 as a channel that binds to NAADP, a second-signaling messenger, resulting in the release of calcium from intracellular stores.
