Actomyosin rings: the riddle of the sphincter.
Contractile rings consisting of actin filaments and myosin-2 have long been known to power cytokinesis, but recent work has shown that single-cell and multicellular actomyosin rings participate in processes ranging from wound healing to extrusion of apoptotic cells from epithelia.
