6KN8, 6KN7 - PubMed Abstract: 
Contraction of striated muscles is driven by cyclic interactions of myosin head projecting from the thick filament with actin filament and is regulated by Ca 2+ released from sarcoplasmic reticulum. Muscle thin filament consists of actin, tropomyosin and troponin, and Ca 2+ binding to troponin triggers conformational changes of troponin and tropomyosin to allow actin-myosin interactions ...
