| Research Abstract |
Thick filaments are composed of more than 300 myosin molecules in myofibrils. In this study, we found that the light meromyosin (LMM), which is one of myosin heavy chain (Myh) domains, was essential to form thick filaments in cultured skeletal muscle cells. Furthermore, to form thick filaments of LMM was facilitated by the presence of the subfragment-2 (S2), although solely expressed S2 did not form thick filaments, suggesting that the S2 may regulate thick filament formation.
