Abstract:
Fluorescence resonance energy transfer study revealed decreased intermonomer mobility of Ca-actin and Mg-actin filaments of myocardial myofibrils in myocardial dystrophy caused by diffuse endocrine disorders, e. g. hypothyrosis. Cis374 axial distance in Ca-actin filament protomer increased in hypothyrosis. Intracellular pH has no effect on inter-monomer mobility of Ca-actin filament.
