WebMay 27, 2024 · Therefore, the thick filament in striated muscles is larger, more complicated and has a higher‐order structure than the nonmuscle bipolar myosin filaments (Dasbiswas, Hu, Schnorrer, Safran, & Bershadsky, 2024). The intricate structure of thick filaments may reduce the exchange rate of myosin molecules in skeletal muscle cells. WebJul 16, 2008 · The HMM contains the head region, termed subfragment 1 (S1), and a portion of the coiled-coil-forming sequence referred to as subfragment 2 (S2) which connects the myosin heads to the thick filament. The LMM is the C-terminal proportion of the rod, which lies along the thick filAMent axis [ 14 ] ( Figure 3 ).
