== Function == | |||
[https://www.uniprot.org/uniprot/URE2_YEAST URE2_YEAST] Plays an important role in nitrogen catabolite repression. Down-regulates the expression of many genes involved in nitrogen utilization by inhibiting the GATA transcriptional activators GLN3 and GAT1. Under good nitrogen conditions, binds to the phosphorylated forms of GLN3 and GAT1 and sequesters them in the cytoplasm, preventing transcription of genes expressed upon nitrogen limitation. Is also an atypical glutaredoxin without a catalytical cysteine residue. Has glutathione peroxidase and thiol:disulfide oxidoreductase activities in both native and fibrillar form. Also shows insulin disulfide reductase and dehydroascorbic acid reductase (DHAR) actvites.<ref>PMID:1990286</ref> <ref>PMID:8755910</ref> <ref>PMID:10604478</ref> <ref>PMID:10799523</ref> <ref>PMID:15371425</ref> <ref>PMID:19321443</ref> | |||
