ATP attaches to the myosin head. Regulatory protein that covers the myosin-binding sites of the actin. Hydrolysis of ATP to ADP and Pi by the ATPase of the myosin head. Triggered by depolarization of the t-tubules. Degrades acetylcholine in the synapse. Neurotransmitter released by somatic neurons at the neuromuscular junction. Calcium binds to this regulatory protein on the thin filaments. Calcium is actively pumped back into the SR.
