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.
Dif1 is required for nuclear import of the R2 subunit and plays an essential role in regulating the dynamic RNR subcellular localization.
Title: Dif1 controls subcellular localization of ribonucleotide reductase by mediating nuclear import of the R2 subunit.

NP_013541.3

Protein that regulates nuclear import of Rnr2p and Rnr4p; phosphorylated by Dun1p in response to DNA damage and degraded; N-terminal half shows similarity to S. pombe Spd1 protein; DIF1 has a paralog, SML1, that arose from the whole genome duplication
