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.

Cell polarity protein Spa2 coordinates Chs2 incorporation at the division site in budding yeast. [PDF]
PLoS Genetics, 2018 Deposition of additional plasma membrane and cargoes during cytokinesis in eukaryotic cells must be coordinated with actomyosin ring contraction, plasma membrane ingression and extracellular matrix remodelling.

iScience, 2023 Summary: Animal cell cytokinesis requires activation of the GTPase RhoA (Rho1 in Drosophila), which assembles an F-actin- and myosin II-dependent contractile ring (CR) at the equatorial plasma membrane.

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 ...

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 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 ...

Rho Family GTPases in Fission Yeast Cytokinesis
Communicative & Integrative Biology, 2019 During cytokinesis, actomyosin ring constriction drives furrow formation. In animal cells, Rho GTPases drive this process through the positioning and assembly of the actomyosin ring, and through extracellular matrix remodeling within the furrow.

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 ...
