WebTroponin I is the inhibitory component of troponin, the thin filament regulatory complex in striated muscle. Separate genes encode cardiac-specific fast and slow skeletal-specific isoforms of this protein. We have previously described gene switching from the slow skeletal to the cardiac troponin I mRNA expression in developing rat heart. WebTroponin, a component of the contractile apparatus of myocardial cells, is a protein complex of three subunits, troponin T (TnT), troponin I (TnI), and troponin C (TnC). TnC is expressed in both cardiac and skeletal muscle, while TnT and TnI are expressed almost exclusively in the heart and commonly referred to as cardiac troponins (cTn).
