Dipartimento cardiovascolare, azienda ospedialiero universitaria ospedali riuniti, trieste. Troponin, or the troponin complex, is a complex of three regulatory proteins troponin c, troponin i, and troponin t that is integral to muscle contraction in skeletal muscle and cardiac muscle, but not smooth muscle.
