A functional link between the histone demethylase PHF8 and the transcription factor ZNF711 in X-linked mental retardation.

abstract：:A chemicogenetic screen was performed in budding yeast mutants that have a weakened replication stress response. This identified an inhibitor of target of rapamycin (TOR) complexes 1 and 2 that selectively enhances the sensitivity of sgs1Δ cells to hydroxyurea and camptothecin. More importantly, the inhibitor has stro...
