Outline of Final Research Achievements

Fission yeast Pot1 binds telomere DNA, and Rqh1 is required for resolution of recombination intermediate. We have shown that the double mutant between pot1 and the helicase-dead point mutant of the RecQ helicase Rqh1 (rqh1-hd) is sensitive to microtubule drug and accumulates recombination intermediates at telomeres. In this research, we found that Spindle assembly checkpoint (SAC)-dependent prometaphase arrest occurred frequently in pot1 rqh1-hd double mutants. Our results indicate that the accumulation of recombination intermediates induces SAC-dependent prometaphase arrest.
