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
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 mutant is resistant to rapamycin; both null mutation and overexpression decrease silencing at rDNA locus and mating type cassette; in systematic studies mutants exhibit sensitivity to tunicamycin and bleomycin, and resistance to hydroxyurea, cycloheximide and fluconazole

- Summary
- DOT6 encodes a helix-turn-helix transcription factor of the Myb family. Dot6p binds PAC (RNA Pol A and C) motifs of the form 5'-GCGATGAGMT-3', which are present in roughly half of all promoters of genes involved in ribosome biogenesis. PAC sites function as Dot6p/Tod6p-dependent repressor elements under stress or poor nutrient conditions. Dot6p functions as a transcriptional repressor whose repressive activity is alleviated by phosphorylation by protein kinase A (PKA) in response to glucose availability. PKA promotes ribosome biogenesis gene expression through inactivation of Dot6p. Glucose deprivation is thereby sufficient to cause repression of ribosome biogenesis. Sch9p responds to glucose availability and phosphorylates Dot6p, possibly reinforcing regulation through PKA. Dot6p appears to effect repression of ribosome biogenesis gene expression at least in part by recruitment of the Rpd3L histone deacetylase complex to ribosome biogenesis gene promoters.
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).
