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 sequence-specific DNA binding transcription factor involved in both allantoin breakdown and nitrogen catabolite activation of transcription from RNA polymerase II promoter; localized to 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; reduction of function decreases utilization of urea s nitrogen source; in systematic studies null mutants show reduced competitive fitness
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.

DAL82 encodes a transcription factor that is not a member of any recognized structural class. It is smaller than most other transcription factors, and contains an N-terminal DNA-binding domain, a central domain required for transcriptional activation, and a C-terminal coiled-coil domain. In the presence of allophanate, which is the last intermediate in the allantoin degradation pathway, Dal82p activates transcription of genes encoding proteins involved in allantoin utilization, such as DAL2, DAL4, DAL5, DAL7, DUR1,2, and DUR3, and also CAR2, encoding ornithine aminotransferase involved in arginine utilization. Dal82p is one of several transcription factors involved in nitrogen source utilization (including Uga3p, Dal82p, Stp1p, and Stp2p) whose function depends on cooperation with the transcription factor Dal81p. The involvement of Dal81p in pathways for utilization of several different nitrogen sources allows the cell to integrate the disparate nutritional signals and to induce different pathways according to availability of each source. Dal82p binds to the UIS-ALL element in the promoters of target genes. Dal82p is able to bind DNA independently of Dal81p, but both Dal81p and Dal82p are required for transcriptional activation. The two transcription factors physically interact, and the DNA-binding domain of Dal81p is not necessary for transcriptional activation in cooperation with Dal82p.
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).
