Abstract: Small-angle X-ray and neutron scattering with contrast variation have made important contributions in advancing our understanding of muscle regulatory protein structures in the context of the dynamic molecular processes governing muscle action. The contributions of the scattering investigations have depended upon the results of key crystallographic, NMR, and electron microscopy experiments that have provided detailed structural information that has aided in the interpretation of the scattering data. This review will cover the advances made using small-angle scattering techniques, in combination with the results from these complementary techniques, in probing the structures of troponin and myosin binding protein C. A focus of the troponin work has been to understand the isoform differences between the skeletal and cardiac isoforms of this major calcium receptor in muscle. In the case of myosin binding protein C, significant data are accumulating, indicating that this protein may act to modulate the primary calcium signals from troponin, and interest in its biological role has grown because of linkages between gene mutations in the cardiac isoform and serious heart disease.
