activity_regulation
ACTIVITY REGULATION: The calcium release is activated by increased cytosolic calcium levels, by nitric oxyde (NO), caffeine and ATP. Channel activity is modulated by the alkaloid ryanodine that binds to the open Ca-release channel with high affinity. At low concentrations, ryanodine maintains the channel in an open conformation. High ryanodine concentrations inhibit channel activity. Channel activity is regulated by calmodulin (CALM). Channel activity is inhibited by magnesium ions, possibly by competition for calcium binding sites. {ECO:0000250|UniProtKB:P11716}.

function
FUNCTION: Cytosolic calcium-activated calcium channel that mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytosol 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+) cytosolic 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. {ECO:0000250|UniProtKB:Q92736, ECO:0000269|PubMed:20431056, ECO:0000269|PubMed:20471962}.

post_translational_modification
PTM: Channel activity is modulated by phosphorylation. Phosphorylation at Ser-2800 and Ser-2806 increases the open probability of the calcium channel. Phosphorylation is increased in failing heart, leading to calcium leaks and increased cytoplasmic Ca(2+) levels (By similarity). {ECO:0000250}.; PTM: Phosphorylation at Ser-2023 by PKA enhances the response to lumenal calcium. {ECO:0000250}.
