Abstract

Calcium (Ca2+) release from intracellular stores controls numerous cellular processes, including cardiac and skeletal muscle contraction, synaptic transmission and metabolism. The ryanodine receptors (RyRs: RyR1, RyR2, RyR3) and inositol 1,4,5-trisphosphate receptors (IP3Rs: IP3R1, IP3R2, IP3R3) are the major Ca2+ release channels (CRCs) on the endo/sarcoplasmic reticulum (ER/SR). RyRs and IP3Rs comprise macromolecular signaling complexes that include modulatory proteins which regulate channel activity in response to extracellular signals resulting in intracellular Ca2+ release. Here we focus on the roles of CRCs in heart, skeletal muscle, brain, metabolism, and aging.
