A novel checkpoint pathway controls actomyosin ring constriction trigger in fission yeast. [PDF]

open access: yesElife, 2020
In fission yeast, the septation initiation network (SIN) ensures temporal coordination between actomyosin ring (CAR) constriction with membrane ingression and septum synthesis. However, questions remain about CAR regulation under stress conditions.

Reconstitution of contractile actomyosin rings in vesicles [PDF]

open access: yesNature Communications, 2020
Abstract One of the grand challenges of bottom-up synthetic biology is the development of minimal machineries for cell division. The mechanical transformation of large-scale compartments, such as Giant Unilamellar Vesicles (GUVs), requires the geometry-specific coordination of active elements, several orders of magnitude larger than ...

Measurement of Contractile Ring Tension Using Two-photon Laser Ablation during Drosophila Cellularization

open access: yesBio-Protocol, 2022
Cytokinesis occurs at the final step of cell division and leads to the separation of daughter cells. It requires assembly and constriction of the actomyosin contractile ring.

Investigating the roles of turnover and mobility in the actomyosin ring of Schizosaccharomyces pombe [PDF]

open access: yes
In many eukaryotes cytokinesis is facilitated by the contraction of an actomyosin ring. The exact mechanisms that lead to this contractility are unknown, although a number of models posit that actin turnover in the ring is essential.

A New Membrane Protein Sbg1 Links the Contractile Ring Apparatus and Septum Synthesis Machinery in Fission Yeast. [PDF]

open access: yesPLoS Genetics, 2016
Cytokinesis in many organisms requires a plasma membrane anchored actomyosin ring, whose contraction facilitates cell division. In yeast and fungi, actomyosin ring constriction is also coordinated with division septum assembly.

Microtubules oppose cortical actomyosin-driven membrane ingression during C. elegans meiosis I polar body extrusion.

open access: yesPLoS Genetics, 2023
During C. elegans oocyte meiosis I cytokinesis and polar body extrusion, cortical actomyosin is locally remodeled to assemble a contractile ring that forms within and remains part of a much larger and actively contractile cortical actomyosin network ...

PP1-Dependent Formin Bnr1 Dephosphorylation and Delocalization from a Cell Division Site. [PDF]

open access: yesPLoS ONE, 2016
Cell cycle ends with cytokinesis that is the physical separation of a cell into two daughter cells. For faithful cytokinesis, cells integrate multiple processes, such as actomyosin ring formation, contraction and plasma membrane closure, into coherent ...

Encapsulated actomyosin patterns drive cell-like membrane shape changes

open access: yesiScience, 2022
Summary: Cell shape changes from locomotion to cytokinesis are, to a large extent, driven by myosin-driven remodeling of cortical actin patterns.

Scar/WAVE has Rac GTPase-independent functions during cell wound repair

open access: yesScientific Reports, 2023
Rho family GTPases regulate both linear and branched actin dynamics by activating downstream effectors to facilitate the assembly and function of complex cellular structures such as lamellipodia and contractile actomyosin rings. Wiskott-Aldrich Syndrome (

Stabilization of the Actomyosin Ring Enables Spermatocyte Cytokinesis in Drosophila [PDF]

open access: yesMolecular Biology of the Cell, 2010
The scaffolding protein anillin is required for completion of cytokinesis. Anillin binds filamentous (F) actin, nonmuscle myosin II, and septins and in cell culture models has been shown to restrict actomyosin contractility to the cleavage furrow. Whether anillin also serves this function during the incomplete cytokinesis that occurs in developing germ
