Ca(2+)-induced movement of tropomyosin on native cardiac thin filaments revealed by cryoelectron microscopy

Muscle contraction relies on the interaction of myosin motors with F-actin, which is regulated through a translocation of tropomyosin by the troponin complex in response to Ca(2+). The current model of muscle regulation holds that at relaxing (low-Ca(2+)) conditions tropomyosin blocks myosin binding...
