The Ringleaders: Understanding the Apicomplexan Basal Complex Through Comparison to Established Contractile Ring Systems [PDF]
Frontiers in Cellular and Infection Microbiology, 2021 The actomyosin contractile ring is a key feature of eukaryotic cytokinesis, conserved across many eukaryotic kingdoms. Recent research into the cell biology of the divergent eukaryotic clade Apicomplexa has revealed a contractile ring structure required ...

Cytokinetic contractile ring structural progression in an early embryo: positioning of scaffolding proteins, recruitment of α-actinin, and effects of myosin II inhibition [PDF]
Frontiers in Cell and Developmental BiologyOur knowledge of the assembly and dynamics of the cytokinetic contractile ring (CR) in animal cells remains incomplete. We have previously used super-resolution light microscopy and platinum replica electron microscopy to elucidate the ultrastructural ...

Measurement of Contractile Ring Tension Using Two-photon Laser Ablation during Drosophila Cellularization [PDF]
Bio-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.

The Mechanosensitive Pkd2 Channel Modulates the Recruitment of Myosin II and Actin to the Cytokinetic Contractile Ring [PDF]
Journal of FungiCytokinesis, the last step in cell division, separates daughter cells through mechanical force. This is often through the force produced by an actomyosin contractile ring.

DrosophilaF-BAR protein Syndapin contributes to coupling the plasma membrane and contractile ring in cytokinesis [PDF]
Open Biology, 2013 Cytokinesis is a highly ordered cellular process driven by interactions between central spindle microtubules and the actomyosin contractile ring linked to the dynamic remodelling of the plasma membrane.

The Myosin-V Myo51 and Alpha-Actinin Ain1p Cooperate during Contractile Ring Assembly and Disassembly in Fission Yeast Cytokinesis [PDF]
Journal of FungiCytokinesis is driven in part by the constriction of a ring of actin filaments, myosin motors and other proteins. In fission yeast, three myosins contribute to cytokinesis including a Myosin-V Myo51.
