Structure of the mitotic checkpoint complex
Web22 hours ago · Cohibin is a mitotic version of the meiotic monopolin complex [24,25], which forms a V-shaped coiled-coil structure that crosslinks kinetochore components and appears to tether rDNA repeats to the nuclear periphery . Unlike cohibin, Fob1 has not previously been implicated in any functions outside the rDNA locus. WebMay 7, 2024 · The mitotic checkpoint monitors kinetochore-microtubule attachment, delays anaphase onset and prevents aneuploidy when unattached or tensionless kinetochores are present in cells. Mitotic arrest deficiency 1 (MAD1) is one of the evolutionarily conserved core mitotic checkpoint proteins.
