ryanodine receptor


Definition: receptor associated with a calcium conductance channel in the sarcoplasmic or endoplasmic reticulum of cells, which when bound to ryanodine, causes the channel to remain in a subconductive state, allowing slow continuing release of calcium ions from the sarcoplasmic reticulum into the cytoplasm. The channels are normally sensitive to calcium ions and not sensitive to inositol triphosphate.
