Based on these results, the genetic engineering on Gat1p has a great potential in enhancing non-preferred nitrogen metabolism in S. cerevisiae.
Title: The modification of Gat1p in nitrogen catabolite repression to enhance non-preferred nitrogen utilization in Saccharomyces cerevisiae.
Data show that the GAT1 gene, encoding a transcriptional activator of nitrogen-responsive catabolic genes, produces a variety of mRNAs differing in their 5' and 3' termini.
Title: Premature termination of GAT1 transcription explains paradoxical negative correlation between nitrogen-responsive mRNA, but constitutive low-level protein production.
We demonstrate that wild type Gat1 isoforms (IsoA and IsoB) are initiated at Gat1 methionines 40, 95, and/or 102, but not at methionine 1 regardless of nitrogen conditions.
Title: Constitutive and nitrogen catabolite repression-sensitive production of Gat1 isoforms.
Rapamycin-dependent Gat1 and Gln3 binding to the Aro80 target promoters is not affected by tryptophan availability, suggesting that transactivation activity of Aro80 is not necessary for the recruitment of GATA factors.
Title: Interplay of Aro80 and GATA activators in regulation of genes for catabolism of aromatic amino acids in Saccharomyces cerevisiae.
Gln3, Gat1, and Ure2 respond to TorC1 and nitrogen availability via distinct regulatory pathways.
Title: Alterations in the Ure2 αCap domain elicit different GATA factor responses to rapamycin treatment and nitrogen limitation.
Controlling lipid fluxes at glycerol-3-phosphate acyltransferase step in yeast: unique contribution of Gat1p to oleic acid-induced lipid particle formation.
Title: Controlling lipid fluxes at glycerol-3-phosphate acyltransferase step in yeast: unique contribution of Gat1p to oleic acid-induced lipid particle formation.
Nitrogen-responsive regulation of GATA protein family activators Gln3 and Gat1 occurs by two distinct pathways, one inhibited by rapamycin and the other by methionine sulfoximine.
Title: Nitrogen-responsive regulation of GATA protein family activators Gln3 and Gat1 occurs by two distinct pathways, one inhibited by rapamycin and the other by methionine sulfoximine.
Gln3 and Gat1 localizations are controlled by two different regulatory pathways
Title: Distinct phosphatase requirements and GATA factor responses to nitrogen catabolite repression and rapamycin treatment in Saccharomyces cerevisiae.
The phosphorylation of Put3p appears to influence the association of Gat1p, but not Gln3p, to the PUT1 promoter.
Title: Mutation of a phosphorylatable residue in Put3p affects the magnitude of rapamycin-induced PUT1 activation in a Gat1p-dependent manner.
Results show that Gat1 is a key factor for the integrated control of nitrogen catabolite repression in Saccharomyces cerevisiae.
Title: The yeast GATA factor Gat1 occupies a central position in nitrogen catabolite repression-sensitive gene activation.
