This study characterized the surface of interaction between Hug1 and the small RNR subunit Rnr2.
Title: Hug1 is an intrinsically disordered protein that inhibits ribonucleotide reductase activity by directly binding Rnr2 subunit.
a novel role for Hug1p as a negative regulator of the MEC1 checkpoint response through its compartmentalization with Rnr2p-Rnr4p.
Title: Cytoplasmic localization of Hug1p, a negative regulator of the MEC1 pathway, coincides with the compartmentalization of Rnr2p-Rnr4p.
In contrast to a deletion of structurally related Difl, Rnr2-Rnr4 subcellular localization is not grossly altered in a Hugl deletion mutant.
Title: Phenotypes associated with Saccharomyces cerevisiae Hug1 protein, a putative negative regulator of dNTP Levels, reveal similarities and differences with sequence-related Dif1.
Two histone deacetylases, RPD3 and HOS2, are required for the activation of DNA damage-inducible genes RNR3 and HUG1.
Title: Histone deacetylases RPD3 and HOS2 regulate the transcriptional activation of DNA damage-inducible genes.

NP_219498.1

Ribonucleotide reductase inhibitor; intrinsically disordered protein that binds to and inhibits Rnr2p; involved in the Mec1p-mediated checkpoint pathway; transcription is induced by genotoxic stress and by activation of the Rad53p pathway; protein abundance increases in response to DNA replication stress
