RL Eur. J. Biochem. 91:231-242(1978).
CC -!- FUNCTION: Troponin is the central regulatory protein of striated muscle
CC contraction. Tn consists of three components: Tn-I which is the
CC inhibitor of actomyosin ATPase, Tn-T which contains the binding site
CC for tropomyosin and Tn-C. The binding of calcium to Tn-C abolishes the
CC inhibitory action of Tn on actin filaments.
CC -!- MISCELLANEOUS: Skeletal muscle troponin C binds four calcium ions.
CC -!- SIMILARITY: Belongs to the troponin C family. {ECO:0000305}.
