function:Troponin is the central regulatory protein of striated muscle contraction. Tn consists of three components: Tn-I which is the inhibitor of actomyosin ATPase, Tn-T which contains the binding site for tropomyosin and Tn-C. The binding of calcium to Tn-C abolishes the inhibitory action of Tn on actin filaments.,miscellaneous:Skeletal muscle troponin C binds four calcium ions.,similarity:Belongs to the troponin C family.,similarity:Contains 4 EF-hand domains.,
