Like all complex organisms, every human originates from a single cell that multiplies through countless cell divisions.

Myosin II, like many molecular motors, is a two-headed dimer held together by a coiled-coil rod. The stability of the (S2) rod has implications for head−head interactions, force generation, and ...

Smooth muscle cells maintain filaments of actin and myosin in the presence of ATP, although dephosphorylated myosin filaments and actin–myosin interactions are unstable under those conditions in vitro ...

How plants maintain this precise positioning is unclear. Myosin XI is a plant-specific motor protein that moves along actin filaments and helps in intracellular organelle transport.
