Spindle assembly checkpoint-dependent mitotic delay is required for cell division in absence of centrosomes [PDF]
eLifeThe spindle assembly checkpoint (SAC) temporally regulates mitosis by preventing progression from metaphase to anaphase until all chromosomes are correctly attached to the mitotic spindle.

TRIP13 is a protein-remodeling AAA+ ATPase that catalyzes MAD2 conformation switching [PDF]
eLife, 2015 The AAA+ family ATPase TRIP13 is a key regulator of meiotic recombination and the spindle assembly checkpoint, acting on signaling proteins of the conserved HORMA domain family.

The spindle assembly checkpoint and speciation [PDF]
PeerJ, 2020 A mechanism is proposed by which speciation may occur without the need to postulate geographical isolation of the diverging populations. Closely related species that occupy overlapping or adjacent ecological niches often have an almost identical genome ...

Modeling Dual Pathways for the Metazoan Spindle Assembly Checkpoint [PDF]
, 2006 Using computational modelling, we investigate mechanisms of signal transduction focusing on the spindle assembly checkpoint where a single unattached kinetochore is able to signal to prevent cell cycle progression.

Ubc1 turnover contributes to the spindle assembly checkpoint in Saccharomyces cerevisiae [PDF]
G3: Genes, Genomes, Genetics, 2021 The spindle assembly checkpoint protects the integrity of the genome by ensuring that chromosomes are properly attached to the mitotic spindle before they are segregated during anaphase.

Caenorhabditis elegans BUB-3 and SAN-1/MAD3 Spindle Assembly Checkpoint Components Are Required for Genome Stability in Response to Treatment with Ionizing Radiation [PDF]
G3: Genes, Genomes, Genetics, 2017 Relatively little is known about the cross-talk between the spindle assembly checkpoint and the DNA damage response, especially in multicellular organisms.

Reverse engineering of the spindle assembly checkpoint. [PDF]
PLoS ONE, 2009 The Spindle Assembly Checkpoint (SAC) is an intracellular mechanism that ensures proper chromosome segregation. By inhibiting Cdc20, a co-factor of the Anaphase Promoting Complex (APC), the checkpoint arrests the cell cycle until all chromosomes are ...

JAK2-CHK2 signaling safeguards the integrity of the mitotic spindle assembly checkpoint and genome stability [PDF]
Cell Death and Disease, 2022 Checkpoint kinase 2 (CHK2) plays an important role in safeguarding the mitotic progression, specifically the spindle assembly, though the mechanism of regulation remains poorly understood.
