Expanding ring-shaped cleavage furrows in multinucleate cells
Molecular Biology of the Cell, 2023 Mitosis in multinucleate cells of a Dictyostelium mutant may be coupled to central cleavage furrows that arise from areas at which dorsal and basal cell cortices are joined. By membrane fusion, holes are formed that by expanding cleave the cell into portions.

PLoS Genetics, 2009 Females homozygous for a mutation in cellular island (cei) produce embryos with defects in cytokinesis during early development. Analysis of the cytoskeletal events associated with furrow formation reveal that these defects include a general delay in ...

Exocyst-Dependent Membrane Addition Is Required for Anaphase Cell Elongation and Cytokinesis in Drosophila. [PDF]
PLoS Genetics, 2015 Mitotic and cytokinetic processes harness cell machinery to drive chromosomal segregation and the physical separation of dividing cells. Here, we investigate the functional requirements for exocyst complex function during cell division in vivo, and ...

Giant FAZ10 is required for flagellum attachment zone stabilization and furrow positioning in Trypanosoma brucei [PDF]
, 2017 The flagellum and flagellum attachment zone (FAZ) are important cytoskeletal structures in trypanosomatids, being required for motility, cell division and cell morphogenesis.

Communicative & Integrative Biology, 2016 In animal cells cytokinesis relies on the contraction of an actomyosin ring that pulls the plasma membrane to create a cleavage furrow, whose ingression finally divides the mother cell into two daughter cells.

Quantitation of the distribution and flux of myosin-II during cytokinesis
BMC Cell Biology, 2002 Background During cytokinesis, the cell's equator contracts against the cell's global stiffness. Identifying the biochemical basis for these mechanical parameters is essential for understanding how cells divide. To achieve this goal, the distribution and

A Three-Dimensional Numerical Model of an Active Cell Cortex in the Viscous Limit
Frontiers in Physics, 2021 The cell cortex is a highly dynamic network of cytoskeletal filaments in which motor proteins induce active cortical stresses which in turn drive dynamic cellular processes such as cell motility, furrow formation or cytokinesis during cell division. Here,

Animal cell cytokinesis: the role of dynamic changes in the plasma membrane proteome and lipidome [PDF]
, 2016 In animal cells, cytokinesis is characterised by the formation of the mitotic spindle that signals the assembly of an actomyosin ring between the spindle poles.

Classical and Emerging Regulatory Mechanisms of Cytokinesis in Animal Cells
Biology, 2019 The primary goal of cytokinesis is to produce two daughter cells, each having a full set of chromosomes. To achieve this, cells assemble a dynamic structure between segregated sister chromatids called the contractile ring, which is made up of filamentous
