WebJan 23, 2024 · Constriction of the actin cytokinetic ring is an essential step of cell division. In a generally accepted view, the constriction is driven by relative sliding of actin filaments propelled by myosin motors. However, in multiple organisms, the ring constriction is myosin independent. How actin rings constrict in the absence of motor activity remains unclear. WebMar 13, 2024 · In this study, we explored the role of the cytokinetic ring component Fic1, first identified by its interaction with the F-BAR protein Cdc15, in septum formation. We found that the fic1 phospho-ablating mutant, fic1-2A , is a gain-of-function allele that suppresses myo2-E1 , the temperature-sensitive allele of the essential type-II myosin, …

WebNov 12, 2024 · When the cytokinetic ring model was implemented, it was known that the nodes and the actin filaments of the cytokinetic ring are essentially constrained to a thin region close to the plasma membrane. Modeling ring formation on a 2D cylindrical surface rather than a 3D volume was an excellent first approximation.
