General Information
Term actomyosin contractile ring ID (Ontology) GO:0005826 (Gene Ontology)
Definition A cytoskeletal structure composed of actin filaments and myosin that forms beneath the plasma membrane of many cells, including animal cells and yeast cells, in a plane perpendicular to the axis of the spindle, i.e. the cell division plane. In animal cells, the contractile ring is located at the cleavage furrow. In budding fungal cells, e.g. mitotic S. cerevisiae cells, the contractile ring forms at the mother-bud neck before mitosis.[ ISBN:0805319409 ISBN:0815316194 PubMed:28914606 ]
Also Known As "CAR" ; "contractile actomyosin ring"
