Comparison of amino acid sequence of troponin I from different striated muscles

Abstract
The sequence of troponin I from fast and slow skeletal and cardiac muscle shows strong homology in the region which binds to actin and is responsible for inhibition of the actomyosin ATPase. More differences are found in the N-terminal region which binds to troponin C. [Chicken fast muscle and rabbit fast muscle, slow muscle and cardiac muscle were studied.].
