Comparison of amino acid sequence of troponin I from different striated muscles.
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 AT Pase. More differences are found in the N-terminal region which binds to troponin C.
