abstract：:While many reports have shown that Ca2+ alone causes ryanodine binding to the heavy fraction of the sarcoplasmic reticulum (HFSR), our results demonstrate that caffeine or beta,gamma-methylene adenosine triphosphate (AMPOPCP) in addition to Ca2+ is necessary for ryanodine binding, although Ca2+ is indispensable for it...
