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.

Kinetic framework of spindle assembly checkpoint signalling [PDF]
Nature Cell Biology, 2013 The mitotic spindle assembly checkpoint (SAC) delays anaphase onset until all chromosomes have attached to both spindle poles. Here, we investigated SAC signalling kinetics in response to acute detachment of individual chromosomes using laser microsurgery. Most detached chromosomes delayed anaphase until they had realigned to the metaphase plate.

Mad3 KEN boxes mediate both Cdc20 and Mad3 turnover, and are critical for the spindle checkpoint [PDF]
, 2007 Mitotic progression is controlled by proteolytic destruction of securin and cyclin. The mitotic E3 ubiquitin ligase, known as the anaphase promoting complex or cyclosome (APC/C), in partnership with its activators Cdc20p and Cdh1p, targets these proteins

MAP kinase meets mitosis: A role for Raf Kinase Inhibitory Protein in spindle checkpoint regulation
Cell Division, 2007 Raf Kinase Inhibitory Protein (RKIP) is an evolutionarily conserved protein that functions as a modulator of signaling by the MAP kinase cascade.

On the regulation of chromosome segregation in human cells : implications of Bub1 Kinase inhibition during cell division [PDF]
, 2015 The maintenance of correct chromosome number (euploidy) during cell division is essential for health. Loss of euploidy is observed in most cancers and is linked to tumorigenesis.

TRIP13 is a protein-remodeling AAA+ ATPase that catalyzes MAD2 conformation switching
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.

Cdk1 inactivation terminates mitotic checkpoint surveillance and stabilizes kinetochore attachments in anaphase [PDF]
, 2014 Two mechanisms safeguard the bipolar attachment of chromosomes in mitosis. A correction mechanism destabilizes erroneous attachments that do not generate tension across sister kinetochores [1].

Requirement for proteolysis in spindle assembly checkpoint silencing [PDF]
Cell Cycle, 2010 Anaphase initiation requires ubiquitin-dependent proteolysis of crucial substrates through activation of the ubiquitin ligase Anaphase promoting Complex/Cyclosome (ApC/C) in association with its coactivator Cdc20. To prevent chromosome segregation errors, effector proteins of a safeguard mechanism called spindle assembly checkpoint (SAC), Mad2 and ...
