WebLight-meromyosin (LMM) is the tail or backbone portion of the molecule, which intertwines with the tails of other myosin molecules to form a thick filament. Heavy-meromyosin (HMM) consists of two subfragments: S-1 and S-2. The S-2 portion of HMM projects out at an angle from LMM, and the S-1 portion is the globular head that can bind to actin.
