WebWe find that TRIP13, aided by the adapter protein p31(comet), converts the HORMA-family spindle checkpoint protein MAD2 from a signaling-active 'closed' conformer to an inactive 'open' conformer. WebTRIP13 is aided in this structural sleight of hand by yet another HORMA-like protein, p31comet (referred to as p31 henceforth), whose C-terminal seatbelt folds back onto itself (Fig. 1A)(25,26, 28, 29). p31 acts as a bridge between TRIP13 and MAD2, stim-ulating TRIP13 to remodel MAD2 and release CDC20 (25, 27).

WebDec 5, 2024 · Because C-Mad2 and O-Mad2 share a common folded core (Fig. 1a), TRIP13–p31 comet catalyzed C-Mad2–O-Mad2 conversion does not necessarily require the global unfolding of Mad2. Local unfolding of the C-terminal region of C-Mad2 can complete this conversion and, in the case of liganded C-Mad2, release the bound ligand.
