Troponin C skeletal muscle is a protein that in humans is encoded by the TNNC2 gene.Troponin (Tn) a key protein complex in the regulation of striated muscle contraction is composed of 3 subunits. The Tn-I subunit inhibits actomyosin ATPase the Tn-T subunit binds tropomyosin and Tn-C while the Tn-C subunit binds calcium and overcomes the inhibitory action of the troponin complex on actin filaments. The protein encoded by this gene is the Tn-C subunit.
