RYR2

Overview
RYR2 ryanodine receptor calcium release channel. Regulates communication between transverse-tubules and sarcoplasmic reticulum. Contraction of cardiac muscle is triggered by release of calcium ions from SR following depolarization of T-tubules. Phosphorylation by PKA dissociates FKBP12.6 from RYR2. Two splice isoforms have been described. Note: This description may include information from UniProtKB.
