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.


Summary
Non-essential gene; null and point mutations confer resistance or sensitivity to various drugs; in large-scale studies, null mutation confers increased competitive fitness in glycerol medium, decreased fitness in minimal medium, and altered resistance to a wide variety of drugs; overexpression causes slow growth
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
The pdr1 null mutant is viable; the null mutant of paralog pdr3 is viable; the pdr1 pdr3 double mutant displays a synthetic growth defect.

Summary
PDR1 encodes a transcription factor that is a member of the C6 zinc finger class, containing a DNA binding domain also known as the Zn2Cys6 binuclear zinc cluster or zinc knuckle. Pdr1p activates transcription of genes involved in pleiotropic drug resistance, such as the ATP-binding cassette transporter genes PDR5, SNQ2, and YOR1, whose products mediate drug efflux from the cell. Pdr1p targets also have roles in hydroxymethylfurfural (HMF) tolerance, ethanol tolerance, the salt stress response, and sphingolipid biosynthesis. Pdr1p binds to multiple PDREs (pleiotropic drug resistance elements) in the promoters of target genes, either as a homodimer or as a heterodimer with other transcription factors, including Pdr3p and Stb5p. PDR3, a paralog of PDR1, is also a target of Pdr1p regulation. Pdr1p is phosphorylated, although the regulatory significance of this is unknown.

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). Click "Expression Details" to view all expression annotations and details for this locus, including a visualization of genes that share a similar expression pattern.
