26544187 p31comet-induced cell death is mediated by interactions with Mad2
26324890 the oligomeric form of TRIP13 binds both p31(comet) and MCC
25092294 joint action of TRIP13 and p31(comet) also promotes the release of Mad2 from MCC, participates in the complete disassembly of MCC and abrogates checkpoint inhibition of APC/C
24596092 attenuating the affinity of p31(Comet) for Mad2 by phosphorylation promotes SAC activity in mitosis. Specifically, phosphorylation of Ser-102 weakens p31(Comet)-Mad2 binding and enhances p31(Comet)-mediated bypass of the SAC.
24131926 Altered p31(Comet):Mad2 expression ratios may provide new insight into altered spindle assembly checkpoint function and the generation of chromosomal instability in tumors.
22566641 The binding of p31(comet) to Mad2 in mitotic checkpoint complex may trigger a conformational change in Cdc20 that facilitates its phosphorylation by Cdk, and that the latter process may promote its dissociation from BubR1.
22544748 the importance of p31(comet) in checkpoint silencing and its potential as a target for antimitotic therapies.
22235654 This review presents knowledge of CMT2 and possible pathogenetic mechanisms responsible for the disease
22100920 p31(comet) negatively regulates the spindle assembly checkpoint by extracting Mad2 from the MCC.
21965286 study found p31(comet) traffics on and off kinetochores and also present in the cytosol; Cells depleted of p31(comet) arrest in metaphase with mature bipolar kinetochore-microtubule attachments; propose that p31(comet) is an essential component of machinery that silences the checkpoint during each cell cycle
21937719 both p31(comet) and ubiquitination of Cdc20 are critical mechanisms of checkpoint inactivation. They act redundantly to promote Mad2 dissociation from Cdc20
21772247 p31comet localizes to kinetochores in a C-Mad2-dependent manner. the Mad1:C-Mad2 complex undergoes regulation by p31comet-dependent 'capping'.
21300909 Although p31(comet) binds to Mad2, it promotes the dissociation of Cdc20 from BubR1 in MCC.
19276188 p31(comet) induces tumor cell senescence by mediating p21(Waf1/Cip1) accumulation and Mad2 disruption and that these effects are dependent on a direct interaction of p31(comet) with Mad2.
18022368 Data suggest that p31(comet)(CMT2) exploits the two-state behavior of Mad2 to block its activation by acting as an "anti-Mad2."
17934339 p31(comet) does not have an impact on the formation of aneuploidy and tetraploidy found in human hepatocellular carcinoma.
15257285 p31(comet, formerly known as Cmt2) counteracts the function of Mad2 and is required for the silencing of the spindle checkpoint
