DSK1, a novel kinesin-related protein from the diatom Cylindrotheca fusiformis that is involved in anaphase spindle elongation. [PDF]
, 1996 We have identified an 80-kD protein that is involved in mitotic spindle elongation in the diatom Cylindrotheca fusiformis. DSK1 (Diatom Spindle Kinesin 1) was isolated using a peptide antibody raised against a conserved region in the motor domain of the ...

Anaphase B Precedes Anaphase A in the Mouse Egg [PDF]
Current Biology, 2012 Segregation of chromosomes at the time of cell division is achieved by the microtubules and associated molecules of the spindle. Chromosomes attach to kinetochore microtubules (kMTs), which extend from the spindle pole region to kinetochores assembled upon centromeric DNA.

A Regulatory Switch Alters Chromosome Motions at the Metaphase-to-Anaphase Transition
Cell Reports, 2016 To achieve chromosome segregation during mitosis, sister chromatids must undergo a dramatic change in their behavior to switch from balanced oscillations at the metaphase plate to directed poleward motion during anaphase.

Bub1-mediated adaptation of the spindle checkpoint. [PDF]
PLoS Genetics, 2011 During cell division, the spindle checkpoint ensures accurate chromosome segregation by monitoring the kinetochore-microtubule interaction and delaying the onset of anaphase until each pair of sister chromosomes is properly attached to microtubules.

A comparison of the distribution of actin and tubulin in the mammalian mitotic spindle as seen by indirect immunofluorescence [PDF]
, 1977 Rabbit antibodies against actin and tubulin were used in an indirect immunofluorescence study of the structure of the mitotic spindle of PtK1 cells after lysis under conditions that preserve anaphase chromosome movement. During early prophase there is no

eLife, 2016 The spindle- and kinetochore-associated (Ska) complex is essential for normal anaphase onset in mitosis. The C-terminal domain (CTD) of Ska1 binds microtubules and was proposed to facilitate kinetochore movement on depolymerizing spindle microtubules ...

Some assembly required: Redefining the mitotic checkpoint
Molecular & Cellular Oncology, 2017 The spindle assembly checkpoint (also known as the spindle or mitotic checkpoint) is a surveillance system that ensures fidelity of chromosome segregation.

Cell Reports, 2015 Condensin is a conserved chromosomal complex necessary to promote mitotic chromosome condensation and sister chromatid resolution during anaphase. Here, we report that yeast condensin binds to replicated centromere regions.

Novel regulation of mitotic exit by the Cdc42 effectors Gic1 and Gic2 [PDF]
, 2004 Copyright @ The Rockefeller University PressThe guanine nucleotide exchange factor Cdc24, the GTPase Cdc42, and the Cdc42 effectors Cla4 and Ste20, two p21-activated kinases, form a signal transduction cascade that promotes mitotic exit in yeast.

CENP-F-dependent DRP1 function regulates APC/C activity during oocyte meiosis I
Nature Communications, 2022 Spindle assembly checkpoint controls anaphase onset and guarantees appropriate chromosome segregation. Here, the authors report that dynamin-related protein 1 is recruited to kinetochores by CENP-F to regulate metaphase-to-anaphase transition by ...
