Skeletal and cardiac muscle contractile activation: tropomyosin "rocks and rolls". Pub. Med. Abstract. Changes in thin filament structure induced by Ca(2+) binding to troponin and subsequent strong cross- bridge binding regulate additional strong cross- bridge attachment, force development, and dependence of force on sarcomere length in skeletal and cardiac muscle. Variations in activation properties account for functional differences between these muscle types.
. ATPase activity of myofibrils, and cardiac or. Substantially more Sr 2+ than Ca 2+ was also required for activation of skeletal muscle actin heavy.
