Actin Depolymerization Drives Actomyosin Ring Contraction during Budding Yeast Cytokinesis [PDF]
Developmental Cell, 2012 SummaryActin filaments and myosin II are evolutionarily conserved force-generating components of the contractile ring during cytokinesis. Here we show that in budding yeast, actin filament depolymerization plays a major role in actomyosin ring ...

Importance of a Myosin II-Containing Progenitor for Actomyosin Ring Assembly in Fission Yeast [PDF]
Current Biology, 2002 An actomyosin-based contractile ring provides the forces necessary for cell cleavage in several organisms [1–3]. Myosin II is an essential component of the actomyosin ring and has also been detected as a “spot” in interphase Schizosaccharomyces pombe ...

The actomyosin ring recruits early secretory compartments to the division site in fission yeast [PDF]
Molecular Biology of the Cell, 2008 The ultimate goal of cytokinesis is to establish a membrane barrier between daughter cells. The fission yeast Schizosaccharomyces pombe utilizes an actomyosin-based division ring that is thought to provide physical force for the plasma membrane ...

A node organization in the actomyosin contractile ring generates tension and aids stability
Molecular Biology of the Cell, 2017 During cytokinesis, a contractile actomyosin ring constricts and divides the cell in two. How the ring marshals actomyosin forces to generate tension is not settled.

The Cortical ER Network Limits the Permissive Zone for Actomyosin Ring Assembly [PDF]
Current Biology, 2010 SummaryPrecise positioning of the cellular division plane is important for accurate segregation of genetic material and determination of daughter cell fates. Here we report a surprising connection between division site positioning and the organization of

Assembly and positioning of actomyosin rings by contractility and planar cell polarity
eLife, 2015 The actomyosin cytoskeleton is a primary force-generating mechanism in morphogenesis, thus a robust spatial control of cytoskeletal positioning is essential.

The Multiple Roles of Cyk1p in the Assembly and Function of the Actomyosin Ring in Budding Yeast
Molecular Biology of the Cell, 1999 The budding yeast IQGAP-like protein Cyk1p/Iqg1p localizes to the mother-bud junction during anaphase and has been shown to be required for the completion of cytokinesis.

Isolation of Cytokinetic actomyosin rings from Saccharomyces cerevisiae and Schizosaccharomyces pombe [PDF]
, 2016 Cytokinesis is the final stage of cell division, through which cellular constituents of mother cells are partitioned into two daughter cells resulting in the increase in cell number.

Dynamics and Stability of the Contractile Actomyosin Ring in the Cell [PDF]
Physical Review Letters, 2022 Contraction of the cytokinetic ring during cell division leads to physical partitioning of a eukaryotic cell into two daughter cells. This involves flows of actin filaments and myosin motors in the growing membrane interface at the mid-plane of the dividing cell.

Self-organized spatial targeting of contractile actomyosin rings for synthetic cell division
Nature CommunicationsA key challenge for bottom-up synthetic biology is engineering a minimal module for self-division of synthetic cells. Actin-based cytokinetic rings are considered a promising structure to produce the forces required for the controlled excision of cell ...
