Troponin-I–induced tropomyosin pivoting defines thin-filament function in relaxed and active muscle
Regulation of the crossbridge cycle that drives muscle contraction involves a reconfiguration of the troponin–tropomyosin complex on actin filaments. By comparing atomic models of troponin–tropomyosin fitted to cryo-EM structures of inhibited and Ca(2+)-activated thin filaments, we find that tropomy...
