A tug of war between filament treadmilling and myosin induced contractility generates actin rings
eLife, 2022 In most eukaryotic cells, actin filaments assemble into a shell-like actin cortex under the plasma membrane, controlling cellular morphology, mechanics, and signaling.

The role of the host—Neutrophil biology
Periodontology 2000, EarlyView., 2023 Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Cell Reports, 2018 Summary: Paxillin is a scaffold protein that participates in focal adhesion signaling in mammalian cells. Fission yeast paxillin ortholog, Pxl1, is required for contractile actomyosin ring (CAR) integrity and collaborates with the β-glucan synthase Bgs1 ...

The actomyosin ring bulks up [PDF]
J Cell Biol, 2011 ![Figure][1] Purple in this heat map indicates that there is more myosin II in a larger contractile ring (left) than in a smaller one (right). Calvert et al. reveal that large fungal cells have more myosin II associated with their contractile rings than do smaller cells, which allows ...

Investigating septin-dependent, actomyosin-ring-independent cytokinesis in Saccharomyces cerevisiae [PDF]
, 2007 In the budding yeast Saccharomyces cerevisiae, a ring of myosin II forms in a septindependent manner at the presumptive budding site in late G1. This ring remains at the bud neck until the onset of cytokinesis, when actin is recruited to it and the ...

Myosin turnover controls actomyosin contractile instability [PDF]
, 2022 Actomyosin contractile force produced by myosin II molecules that bind and pull actin filaments is harnessed for diverse functions, from cell division by the cytokinetic contractile ring to morphogenesis driven by supracellular actomyosin networks during

The recruitment of acetylated and unacetylated tropomyosin to distinct actin polymers permits the discrete regulation of specific myosins in fission yeast. [PDF]
, 2010 Tropomyosin (Tm) is a conserved dimeric coiled-coil protein, which forms polymers that curl around actin filaments in order to regulate actomyosin function.

Biology Open, 2017 When cells in epithelial sheets are damaged by intrinsic or extrinsic causes, they are eliminated by extrusion from the sheet. Cell extrusion, which is required for maintenance of tissue integrity, is the consequence of contraction of actomyosin rings ...

Septum development in Neurospora crassa: the septal actomyosin tangle. [PDF]
PLoS ONE, 2014 Septum formation in Neurospora crassa was studied by fluorescent tagging of actin, myosin, tropomyosin, formin, fimbrin, BUD-4, and CHS-1. In chronological order, we recognized three septum development stages: 1) septal actomyosin tangle (SAT) assembly ...
