Cytokinetic ring
Animal cell cytokinesis begins shortly after the onset of sister chromatid separation in the anaphase of mitosis. The process can be divided to the following distinct steps: anaphase spindle reorganization, division plane specification, actin-myosin ring assembly and contraction, and abscission. Faithful partitioning of the genome to emerging daughter cells is ensured thro… WebFeb 8, 2024 · During cytokinesis, actomyosin ring contraction remodels the cellular cortex to generate a cleavage furrow and then, the midbody, a platform for the assembly of the abscission machinery that controls the final separation of daughter cells (1, 2).Although the overall progression of cytokinesis is well-documented, many questions remain, especially …

WebOct 17, 2011 · Cytokinesis in Escherichia coli and other bacteria is mediated by a ring-shaped multiprotein machine called the “septal ring” or “divisome” ( 1 ). Assembly of this machine begins with the polymerization of the tubulin-like FtsZ protein into a ring-like structure just underneath the cell membrane at the prospective site of division ( 2 ). WebIn 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. fic1phospho-ablating mutant, fic1-2A, is a gain-of-function allele that suppresses myo2-E1, the temperature-sensitive allele of the essential type-II myosin,
