STRUCTURES OF THE APO AND CALCIUM TROPONIN-C REGULATORY DOMAINS: THE MUSCLE CONTRACTION SWITCH


Overview

Regulation of contraction in skeletal muscle occurs through calcium binding to the protein troponin C. The solution structures of the regulatory domain of apo and calcium-loaded troponin C have been determined by multinuclear, multidimensional nuclear magnetic resonance techniques. The structural transition in the regulatory domain of troponin C on calcium binding involves an opening of the structure through large changes in interhelical angles. This leads to the increased exposure of an extensive hydrophobic patch, an event that triggers skeletal muscle contraction.
