## Abstract The N‐terminal regulatory region of Troponin I, residues 1–40 (TnI 1–40, regulatory peptide) has been shown to have a biologically important function in the interactions of troponin I and troponin C. Truncated analogs corresponding to shorter versions of the N‐terminal region (1–30, 1–2

The Ca(2+)/Mg(2+)-dependent interactions between TnC and TnI play a critical role in regulating the 'on' and 'off' states of muscle contraction as well as maintaining the structural integrity of the troponin complex in the off state. In the present study, we have investigated the binding interaction
