Molecular bases of regulation of cardiac muscle contractility

Regulation of heart contractility is operated by both thin, actin containing filaments, and thick, myosin containing filaments. Ca2+-induced structural changes in the regulatory...心脏收缩力的调控由两类肌丝共同介导：一类为含有肌动蛋白(actin)的细肌丝，另一类为含有肌球蛋白(myosin)的粗肌丝。钙离子(Ca²+)诱导的调控区域结构变化...
