Phospho-KNL-1 recognition by a TPR domain targets the BUB-1-BUB-3 complex to C. elegans kinetochores.
Title: Phospho-KNL-1 recognition by a TPR domain targets the BUB-1-BUB-3 complex to C. elegans kinetochores.
the cdc-20 gain-of-function mutant cdc-20/fzy-1(av15), which is refractory to the cell cycle delay conferred by the spindle checkpoint, showed phenotypes similar to bub-3 and san-1 mutants. We speculate that BUB-3 is involved in the DNA damage response through regulation of cell cycle timing.
