Actomyosin Ring Formation and Tension Generation in Eukaryotic Cytokinesis [PDF]
Current Biology, 2016 Cell division facilitated by a contractile ring is an almost universal feature across all branches of cellular life, with the notable exception of higher plants.

Nonmedially assembled F-actin cables incorporate into the actomyosin ring in fission yeast [PDF]
Journal of Cell Biology, 2012 In many eukaryotes, cytokinesis requires the assembly and constriction of an actomyosin-based contractile ring. Despite the central role of this ring in cytokinesis, the mechanism of F-actin assembly and accumulation in the ring is not fully understood ...

Coordinated cortical ER remodeling facilitates actomyosin ring assembly
Current Biology, 2022The cortical endoplasmic reticulum (cER) is a reticulated network closely attached to the plasma membrane (PM). In the fission yeast Schizosaccharomyces pombe (S. pombe), ER-PM contacts have been suggested to restrict both the allocation and compaction of large-sized actomyosin assemblies along the lateral cell cortex. However, how cells orchestrate ER-

Nature Cell Biology, 2008 By rapidly depleting each of the essential budding yeast proteins of unknown function, we identified a novel factor that we call Inn1, which associates with the contractile actomyosin ring at the end of mitosis and is needed for cytokinesis. We show that

Dynamics of actomyosin filaments in the contractile ring revealed by ultrastructural analysis
Genes to Cells, 2023AbstractCytokinesis, the final process of cell division, involves the accumulation of actin and myosin II filaments at the cell's equator, forming a contractile ring that facilitates the division into two daughter cells. While light microscopy has provided valuable insights into the molecular mechanism of this process, it has limitations in examining ...

Modeling cytokinesis of eukaryotic cells driven by the actomyosin contractile ring
International Journal for Numerical Methods in Biomedical Engineering, 2016 SummaryA three‐dimensional (3D) hydrodynamic model for cytokinesis of eukaryotic cells is developed, in which we model dynamics of actomyosins in the cell cortex, in particular, along the cytokinetic ring formed in the cortex and in the neighborhood of the cell's division plane explicitly.

Current Biology, 1998 Background: An actomyosin-based contractile ring plays a pivotal role in cytokinesis. Despite the identification of many components of the ring, the steps involved in its assembly are unknown.

Cardiovascular Research, 2018 AimsAfter birth mammalian cardiomyocytes initiate a last cell cycle which results in binucleation due to cytokinesis failure. Despite its importance for cardiac regenerative therapies, this process is poorly understood.
