the cc401-type tropomyosin , unlike other smooth muscle or cytoskeletal tropomyosins , thus retains two muscle-type troponin-binding regions , for troponin i at amino acid residues 41-80 and for troponin t near amino acid residue 190 , while switching to a different troponin binding site at residues 258-284 .
