GONUTS is under stress! The website is currently experiencing long-wait times and frequent time-outs due to the record number of students, groups, and annotations related to CACAO this semester. We are currently working on increasing performance -- please accept our apologies for the technical difficulties.
You can help reduce stress on the server by:
- not reloading pages frequently - this just adds
- opening links in new windows (so you can read the old page)
Category:GO:0005826 ! actomyosin contractile ring
name: actomyosin contractile ring
namespace: cellular_component
alt_id:GO:0030480
def: "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. Ring contraction is associated with centripetal growth of the membrane that divides the cytoplasm of the two daughter cells. In animal cells, the contractile ring is located inside the plasma membrane at the location of the cleavage furrow. In budding fungal cells, e.g. mitotic S. cerevisiae cells, the contractile ring forms beneath the plasma membrane at the mother-bud neck before mitosis."
