Curvature-induced expulsion of actomyosin bundles during cytokinetic ring contraction [PDF]
eLife, 2016 Many eukaryotes assemble a ring-shaped actomyosin network that contracts to drive cytokinesis. Unlike actomyosin in sarcomeres, which cycles through contraction and relaxation, the cytokinetic ring disassembles during contraction through an unknown ...

Equatorial Assembly of the Cell-Division Actomyosin Ring in the Absence of Cytokinetic Spatial Cues [PDF]
Current Biology, 2018 The position of the division site dictates the size and fate of daughter cells in many organisms. In animal cells, division-site placement involves overlapping mechanisms, including signaling from the central spindle microtubules, astral microtubules ...

Motor Activity Dependent and Independent Functions of Myosin II Contribute to Actomyosin Ring Assembly and Contraction in Schizosaccharomyces Pombe [PDF]
Current Biology, 2017 Cytokinesis depends on a contractile actomyosin ring in many eukaryotes [1, 2, 3]. Myosin II is a key component of the actomyosin ring, although whether it functions as a motor or as an actin cross-linker to exert its essential role is disputed [1, 4, 5].

Myo2p is the major motor involved in actomyosin ring contraction in fission yeast. [PDF]
Curr Biol, 2017 Cytokinesis in many eukaryotes requires an actomyosin-based contractile ring [1]. In fission yeast, cytokinesis involves the type II myosins Myo2p and Myp2p and the type V myosin Myo51p [2]. A recent study by Laplante et al.

Actomyosin ring formation and tension generation in eukaryotic cytokinesis [PDF]
Current Biology, 2016 Cell division facilitated by a contractile ring is an almost universal feature across all branches of cellular life, with the notable exception of higher plants.

The actomyosin ring recruits early secretory compartments to the division site in fission yeast [PDF]
Molecular Biology of the Cell, 2008 The ultimate goal of cytokinesis is to establish a membrane barrier between daughter cells. The fission yeast Schizosaccharomyces pombe utilizes an actomyosin-based division ring that is thought to provide physical force for the plasma membrane ...

Importance of a Myosin II-Containing Progenitor for Actomyosin Ring Assembly in Fission Yeast [PDF]
Current Biology, 2002 An actomyosin-based contractile ring provides the forces necessary for cell cleavage in several organisms [1–3]. Myosin II is an essential component of the actomyosin ring and has also been detected as a “spot” in interphase Schizosaccharomyces pombe ...

Isolation of Cytokinetic actomyosin rings from Saccharomyces cerevisiae and Schizosaccharomyces pombe [PDF]
, 2016 Cytokinesis is the final stage of cell division, through which cellular constituents of mother cells are partitioned into two daughter cells resulting in the increase in cell number.

The Cortical ER Network Limits the Permissive Zone for Actomyosin Ring Assembly [PDF]
Current Biology, 2010 SummaryPrecise positioning of the cellular division plane is important for accurate segregation of genetic material and determination of daughter cell fates. Here we report a surprising connection between division site positioning and the organization of
