中文摘要

RyR2的N端和中心结构域之间的结构域间相互作用缺陷降低了CaM与RyR2的结合亲和力,从而导致患病心脏中的自发性Ca^2+释放事件。纠正钙调素结合缺陷可能是一种新的策略,以防止异常的Ca^2+释放在心力衰竭和致命性心律失常。
英文摘要
The defective inter-domain interaction between N-terminal and central domains within RyR2 reduces the binding affinity of CaM to RyR2, thereby causing the spontaneous Ca^<2+> release events in diseased hearts. Correction of the defective CaM binding may be a new strategy to protect against the aberrant Ca^<2+> release in heart failure and lethal arrhythmia.
