Troponin ( Tn ) is a regulatory protein of muscle contraction. It is located on the fine myofilaments of the contractile protein and plays an important regulatory role in the process of muscle contraction and relaxation. It contains three subtypes: fast response , slow response and cardiac troponin ( cTn ) . The first two are associated with skeletal muscle , while cardiac troponin is found only in cardiomyocytes and is a complex composed of three subunits: troponin T ( cTn ) , troponin I ( cTnI ) , and troponin C ( cTnC ) . cTnT and cTnI are antigens specific to cardiomyocytes that degrade from myocardial fibers when cardiomyocytes are damaged. The increase of cTn in serum reflects the damage of cardiomyocytes , and its specificity and sensitivity are higher than those of the commonly used myocardial enzyme profiles.
