Gene Ontology Details

Gene Ontology

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code. SGD has manually curated and high-throughput GO Annotations, both derived from the literature, as well as computational, or predicted, annotations. Click "Gene Ontology Details" to view all GO information and evidence for this locus as well as biological processes it shares with other genes.

Phenotype Details

Phenotype

Phenotype annotations for a gene are curated single mutant phenotypes that require an observable (e.g., "cell shape"), a qualifier (e.g., "abnormal"), a mutant type (e.g., null), strain background, and a reference. In addition, annotations are classified as classical genetics or high-throughput (e.g., large scale survey, systematic mutation set). Whenever possible, allele information and additional details are provided. Click "Phenotype Details" to view all phenotype annotations and evidence for this locus as well as phenotypes it shares with other genes.


Interaction Details

Interaction

Interaction annotations are curated by BioGRID and include physical or genetic interactions observed between at least two genes. An interaction annotation is composed of the interaction type, name of the interactor, assay type (e.g., Two-Hybrid), annotation type (e.g., manual or high-throughput), and a reference, as well as other experimental details. Click "Interaction Details" to view all interaction annotations and evidence for this locus, including an interaction visualization.

Summary
USV1 encodes a transcription factor containing a C2H2 zinc finger. Usv1p activates transcription of genes involved in respiratory metabolism, such as ACS1, IDH1, and CIT2, and also activates transcription of the ENA1 gene involved in salt and alkaline pH stress tolerance. In large-scale experiments, Usv1p has been found to be required for hyperosmotic stress resistance, and to bind to the promoter of the FLO11 gene involved in filamentous growth and flocculation. Transcription of USV1 is regulated by the transcription factors Adr1p and Nrg1p. Expression is not detectable during growth on glucose, but is activated on nonfermentable carbon sources and in the presence of high salt. USV1 transcription was also found to be differentially regulated in distinct subpopulations of cells within a growing colony. USV1 has a paralog, RGM1, that encodes a putative transcription factor.

Expression Details

Expression

Expression data are derived from records contained in the Gene Expression Omnibus (GEO), and are first log2 transformed and normalized. Referenced datasets may contain one or more condition(s), and as a result there may be a greater number of conditions than datasets represented in a single clickable histogram bar. The histogram division at 0.0 separates the down-regulated (green) conditions and datasets from those that are up-regulated (red).
