WebApr 28, 2015 · TRIP13 then unfolds a part of the MAD2 protein, converting MAD2 into the open shape. Ye et al. propose that, once all chromosomes are lined up on the spindle, TRIP13 turns off the spindle assembly checkpoint by converting closed MAD2 to open MAD2. Also, when cells are not undergoing cell division, TRIP13 may maintain MAD2 in … WebNov 20, 2024 · Molecular modelling suggests that by gripping MAD2 NT within its axial pore, TRIP13 couples sequential ATP-driven translocation of its hexameric ring along MAD2 NT to push upwards on, and simultaneously rotate, the globular domains of the p31 comet -C-MAD2 complex. This unwinds a region of the αA helix of C-MAD2 that is required to …
WebThe AAA-ATPase thyroid hormone receptor interacting protein 13 (TRIP13), jointly with the Mad2-binding protein p31 comet, promotes the inactivation of the mitotic (spindle assembly) checkpoint by disassembling the mitotic checkpoint complex (MCC).This checkpoint system ensures the accuracy of chromosome segregation by delaying … WebOct 19, 2024 · In vitro, TRIP13 and its Mad2-binding adapter protein p31 comet have been shown to convert C-Mad2 to O-Mad2 50 and to release Mad2 from Cdc20:C-Mad2 or the four-protein MCC 47, 48, 64. These findings, plus reports that RNAi-mediated reduction of TRIP13 can slow mitotic exit in some cells 49 , have led to the idea that TRIP13 and p31 …
