...Fiona O'Brien; Elisa Venturi; Rebecca Sitsapesan Once opened, ryanodine receptors (RyR) are efficient pathways for the release of Ca 2+ from the endoplasmic/sarcoplasmic reticulum (ER/SR). The precise nature of the Ca 2+ -release event, however, requires fine-tuning for the specific process...

... (sarcoplasmic reticulum) calcium release channel in triggering arrhythmias. Mutant RyR2 channels give rise to spontaneous release of calcium (Ca 2+ ) from the SR during diastole, which enhances the probability of ventricular arrhythmias. Several molecular mechanisms have been proposed to explain the gain...

...T. Kamishima; J.M. Quayle Ca 2+ influx across plasma membranes may trigger Ca 2+ release by activating ryanodine-sensitive receptors in the sarcoplasmic reticulum. This process is called Ca 2+ -induced Ca 2+ release, and may be important in regulating cytosolic Ca 2+ concentration ([Ca 2+ ] i...
