Loss of function of the Cik1/Kar3 motor complex results in chromosomes with syntelic attachment that are sensed by the tension checkpoint. [PDF]

open access: yesPLoS Genetics, 2012
The attachment of sister kinetochores by microtubules emanating from opposite spindle poles establishes chromosome bipolar attachment, which generates tension on chromosomes and is essential for sister-chromatid segregation.

Accurate chromosome segregation by probabilistic self-organization [PDF]

open access: yesBMC Biology 2015 13:65, 2014
Background: For faithful chromosome segregation during cell division, correct attachments must be established between sister chromosomes and microtubules from opposite spindle poles through kinetochores (chromosome bi-orientation). Incorrect attachments of kinetochore microtubules (kMTs) lead to chromosome mis-segregation and aneuploidy, which is often

Smurf2 as a novel mitotic regulator: From the spindle assembly checkpoint to tumorigenesis

open access: yesCell Division, 2009
The execution of the mitotic program with high fidelity is dependent upon precise spatiotemporal regulation of posttranslational protein modifications.

Some assembly required: Redefining the mitotic checkpoint

open access: yesMolecular & 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.

Running on a treadmill: dynamic inhibition of APC/C by the spindle checkpoint

open access: yesCell Division, 2007
During mitosis, the genome duplicated during S-phase is synchronously and accurately segregated to the two daughter cells. The spindle checkpoint prevents premature sister-chromatid separation and mitotic exit.

Natural Loss of Mps1 Kinase in Nematodes Uncovers a Role for Polo-like Kinase 1 in Spindle Checkpoint Initiation

open access: yesCell Reports, 2015
The spindle checkpoint safeguards against chromosome loss during cell division by preventing anaphase onset until all chromosomes are attached to spindle microtubules.

The coordination of centromere replication, spindle formation, and kinetochore-microtubule interaction in budding yeast. [PDF]

open access: yesPLoS Genetics, 2008
The kinetochore is a protein complex that assembles on centromeric DNA to mediate chromosome-microtubule interaction. Most eukaryotic cells form the spindle and establish kinetochore-microtubule interaction during mitosis, but budding yeast cells finish ...

Sustained spindle-assembly checkpoint response requires de novo transcription and translation of cyclin B1.

open access: yesPLoS ONE, 2010
Microtubule-targeting drugs induce mitotic delay at pro-metaphase by preventing the spindle assembly checkpoint to be satisfied. However, especially after prolonged treatments, cells can escape this arrest in a process called mitotic slippage.

Unveil Sleep Spindles with Concentration of Frequency and Time [PDF]

open access: yesarXiv, 2023
Objective: Sleep spindles contain crucial brain dynamics information. We introduce the novel non-linear time-frequency analysis tool 'Concentration of Frequency and Time' (ConceFT) to create an interpretable automated algorithm for sleep spindle annotation in EEG data and to measure spindle instantaneous frequencies (IFs).

Bub1 is a fission yeast kinetochore scaffold protein, and is sufficient to recruit other spindle checkpoint proteins to ectopic sites on chromosomes. [PDF]

open access: yesPLoS ONE, 2007
The spindle checkpoint delays anaphase onset until all chromosomes have attached in a bi-polar manner to the mitotic spindle. Mad and Bub proteins are recruited to unattached kinetochores, and generate diffusible anaphase inhibitors.
