The genome maintenance factor Mgs1 is targeted to sites of replication stress by ubiquitylated PCNA.

Saugar I, Parker JL, Zhao S, Ulrich HD

Mgs1, the budding yeast homolog of mammalian Werner helicase-interacting protein 1 (WRNIP1/WHIP), contributes to genome stability during undisturbed replication and in response to DNA damage. A ubiquitin-binding zinc finger (UBZ) domain directs human WRNIP1 to nuclear foci, but the functional significance of its presence and the relevant ubiquitylation targets that this domain recognizes have remained unknown. Here, we provide a ... [more]
