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.

A RNA polymerase II transcription factor that binds specific DNA sequence; negatively regulates transcription and is involved in nitrogen catabolite repression of transcription; localized to the nucleus

Phenotype Details


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.

Non-essential gene; null mutant displays elevated expression of several genes controlled by nitrogen catabolite repression system; both null mutation and overexpression in strain Sigma1278b cause increased filamentous growth
Interaction Details


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.

The dal80 null mutant is viable; the null mutant of paralog gzf3 is viable; the dal80 gzf3 double mutant has not been annotated for phenotype.

DAL80 encodes a transcriptional repressor that is a member of the C4 or GATA class. The repressors Dal80p and Gzf3p and the transcriptional activators Gat1p and Gln3p, all members of the GATA class with homologous zinc fingers, bind to the same core consensus sequence and collectively regulate the nitrogen catabolite repression (NCR) pathway, which controls a set of at least 90 genes required for uptake and utilization of different nitrogen sources. Dal80p exerts its repressive effect by three different mechanisms: repression of the genes encoding the activators Gat1p and Gln3p; competition with Gat1p and Gln3p for binding at the promoters of NCR target genes; and direct repression of NCR target genes. DAL80 transcription is regulated by the NCR pathway, primarily by autoregulation and by Gln3p regulation. In addition, the four GATA factors interact with each other to form homodimers or multiple different heterodimers, allowing for fine-tuning of NCR regulation.
Expression Details


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).
