This gene encodes a ryanodine receptor found in cardiac muscle sarcoplasmic reticulum. The encoded protein is one of the components of a calcium channel, composed of a tetramer of the ryanodine receptor proteins and a tetramer of FK506 binding protein 1B proteins, that supplies calcium to cardiac muscle. Mutations in this gene are associated with stress-induced polymorphic ventricular tachycardia and arrhythmogenic right ventricular dysplasia. [provided by RefSeq, Jul 2008]
GeneCards Summary for RYR2 Gene
RYR2 (Ryanodine Receptor 2 (Cardiac)) is a Protein Coding gene. Diseases associated with RYR2 include ryr2-related catecholaminergic polymorphic ventricular tachycardia and ventricular tachycardia, catecholaminergic polymorphic, 1. Among its related pathways are Activation of cAMP-Dependent PKA and CREB Pathway. GO annotations related to this gene include calcium ion binding and protein kinase binding. An important paralog of this gene is RYR1.
UniProtKB/Swiss-Prot for RYR2 Gene
Calcium channel that mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytoplasm and thereby plays a key role in triggering cardiac muscle contraction. Aberrant channel activation can lead to cardiac arrhythmia. In cardiac myocytes, calcium release is triggered by increased Ca(2+) levels due to activation of the L-type calcium channel CACNA1C. The calcium channel activity is modulated by formation of heterotetramers with RYR3. Required for cellular calcium ion homeostasis. Required for embryonic heart development.
The ryanodine receptors (RyRs) are a family of Ca2+ channels that mediate the release of Ca2+ from intracellular Ca2+ storage organelles. Three RyR isoforms have been identified to date, RyR1, RyR2 and RyR3, roles of which include contraction, secretion and synaptic transmission.
