Cellular component - Cleavage furrow
In fungal, amoeboid and animal cells, during the cytokinesis at the end of cell division, a cleavage furrow forms in the plasma membrane. A contractile ring containing actin and myosin is assembled at the selected site of the future cleavage furrow. Ring contraction produces the force to constrict the cleavage furrow and the daughter cells separate by membrane fusion.
