WebMitotic kinetochores are initially captured by dynamic microtubules via a ‘search-and-capture’ mechanism. The microtubule motor, dynein, is critical for kinetochore capture as it has been shown to transport microtubule-attached chromosomes towards the spindle pole during early mitosis. WebThe spindle assembly checkpoint (SAC) involves the MAD (mitotic arrest deficient) proteins MAD1, MAD2, BUBR1 (MAD3), and BUB1. 24 To complete mitosis, the cell …

WebThe APC/C is the principle target of the mitotic checkpoint, which prevents segregation while chromosomes are unattached to spindle microtubules. We now report the identification and characterization of APC16, a conserved subunit of the APC/C. APC16 was found in association with tandem-affinity-purified mitotic checkpoint complex protein complexes.
