Ryanodine sensitizes the cardiac Ca(2+) release channel (ryanodine receptor isoform 2) to Ca(2+) activation and dissociates as the channel is closed by Ca(2+) depletion
In single-channel recordings, the rabbit cardiac Ca(2+) release channel (RyR2) is converted to a fully open subconductance state with about 50% of full conductance by micromolar concentrations of ryanodine. At +30 mV, corresponding to a luminal to cytoplasmic cation current, the probability of openi...
