Troponin chymotryptic subfragments

Both of two chymotryptic subfragments, troponin T1 and T2 , bind to tropomyosin (Ohtsuki, 1979b Tanokura et al., 1982 Pearlstone and Smillie, 1981, 1982). Thus two regions of troponin T are involved in the... 

Seven chymotryptic subfragments of troponin T have been isolated troponin Ti (residues 1-158), troponin T2 (residues 159-259), troponin T2 (residues 156-259), troponin T2/3I (residues 159-242), tro-...

The fine axial orientation of troponin T was then demonstrated using the antibodies against chymotryptic troponin T subfragments, i.e., troponin T1 (MW 18,700) and troponin T2 (MW 11,900) of chicken skeletal muscle (Ohtsuki, 1979b). Anti-troponin T2 stained the same position as that stained by the antibodies against troponin I and C, whereas antitroponin T1 stained a position 13 nm toward the Z line from that stained by anti-troponin T2. Thus each member of the striation pair formed by anti-troponin T was proved to be derived from different regions in the molecule.
