Troponin C, skeletal muscle, TNNC2.
Troponin-C2 (Troponin C, skeletal muscle) is the central regulatory antigen of striated muscle contraction, and modulates the Ca2+-activation characteristics of muscle fibers. Troponin-C2 has three subunits, Troponin I(Tn-1), Troponin T(Tn-T) and Troponin C(Tn-C). Tn-I subunit inhibits actomyosin ATPase and Tn-T subunit binds tropomyosin and Tn-C, while Tn-C subunit binds calcium and overcomes the inhibitory action of the troponin complex on actin filaments. Mutations in all components of this complex have been linked with skeletal muscle disease.
Troponin-C2 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain of 160 amino acids having a molecular mass of 18.1kDa. The Recombinant Human Troponin-C2 is purified by proprietary chromatographic techniques.
The protein (1mg/ml) contains 20 mM Tris-HCl buffer (pH 7.5), 1mM DTT, 100mM NaCl and 10% glycerol.
