WebGeneral description. Troponin is a complex of three regulatory proteins (Troponin I, Troponin T and Troponin C). It is located on the actin filament and is essential for the calcium-mediated regulation of skeletal and cardiac muscle contraction. ... (Cardiac Troponin I and T) are released when the heart muscle has been damaged, such as … WebCardiac muscle contraction occurs via the sliding filament model of contraction, much like skeletal muscle. Once calcium is bound to troponin-C and the conformational change of tropomyosin has occurred, myosin heads can bind to actin. Following this ADP and inorganic phosphate are released from the myosin head so the power stroke can occur.
