The synaptonemal complex protein Zip1 promotes bi-orientation of centromeres at meiosis I. [PDF]

open access: yesPLoS Genetics, 2009
In meiosis I, homologous chromosomes become paired and then separate from one another to opposite poles of the spindle. In humans, errors in this process are a leading cause of birth defects, mental retardation, and infertility.

Protein phosphatase 1 in association with Bud14 inhibits mitotic exit in Saccharomyces cerevisiae

open access: yeseLife, 2021
Mitotic exit in budding yeast is dependent on correct orientation of the mitotic spindle along the cell polarity axis. When accurate positioning of the spindle fails, a surveillance mechanism named the spindle position checkpoint (SPOC) prevents cells ...

TRIP13PCH-2 promotes Mad2 localization to unattached kinetochores in the spindle checkpoint response. [PDF]

open access: yes, 2015
The spindle checkpoint acts during cell division to prevent aneuploidy, a hallmark of cancer. During checkpoint activation, Mad1 recruits Mad2 to kinetochores to generate a signal that delays anaphase onset.

Comment on "A centrosome-independent role for gamma-TuRC proteins in the spindle assembly checkpoint" [PDF]

open access: yes, 2007
Müller et al. (Reports, 27 October 2006, p. 654) showed that inhibition of the γ-tubulin ring complex (γ-TuRC) activates the spindle assembly checkpoint (SAC), which led them to suggest that γ-TuRC proteins play molecular roles in SAC activation. Because

BubR1 is frequently repressed in acute myeloid leukemia and its re-expression sensitizes cells to antimitotic therapy

open access: yesHaematologica, 2013
Spindle poison-based therapy is of only limited benefit in acute myeloid leukemia while lymphoblastic leukemia/lymphoma responds well. In this study, we demonstrated that the spindle assembly checkpoint protein BubR1 was down-regulated in the vast ...

Checkpoint proteins come under scrutiny [PDF]

open access: yes, 2013
Details are emerging of the interactions between the kinetochore and various spindle checkpoint proteins that ensure that sister chromatids are equally divided between daughter cells during cell ...

Use of the Protein Ontology (PRO) for Multi-Faceted Analysis of Biological Processes: a Case Study of the Spindle Checkpoint

open access: yesFrontiers in Genetics, 2013
As a member of the Open Biomedical Ontologies (OBO) foundry, the Protein Ontology (PRO) provides an ontological representation of protein forms and complexes and their relationships.

Bub1 kinase in the regulation of mitosis

open access: yesAnimal Cells and Systems, 2021
Accurate chromosome segregation is required for cell survival and organismal development. During mitosis, the spindle assembly checkpoint acts as a safeguard to maintain the high fidelity of mitotic chromosome segregation by monitoring the attachment of ...

Mammalian kinetochores count attached microtubules in a sensitive and switch-like manner. [PDF]

open access: yes, 2019
The spindle assembly checkpoint (SAC) prevents anaphase until all kinetochores attach to the spindle. Each mammalian kinetochore binds many microtubules, but how many attached microtubules are required to turn off the checkpoint, and how the kinetochore ...

The chromosomal passenger complex and the spindle assembly checkpoint: kinetochore-microtubule error correction and beyond

open access: yesCell Division, 2008
During mitosis, correct bipolar chromosome attachment to the mitotic spindle is an essential prerequisite for the equal segregation of chromosomes. The spindle assembly checkpoint can prevent chromosome segregation as long as not all chromosome pairs ...
