Abstract

The evolutionarily conserved yeast checkpoint protein kinase Rad53 regulates cell cycle progression, transcription, and DNA repair in response to DNA damage. To uncover potential regulatory targets of Rad53, we identified proteins physically associated with it in vivo using protein affinity purification and tandem mass spectrometry. Here we report that Rad53 interacts in a dynamic functional manner with Asf1, a chromatin assembly factor recently shown to mediate deposition of acetylated histones H3 and H4 onto newly replicated DNA. Biochemical and molecular genetic studies suggest that Asf1 is an important target of the Rad53-dependent DNA damage response and that Rad53 may directly regulate chromatin assembly during DNA replication and repair.
