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
- STB3 encodes a ribosomal RNA processing element (RRPE; 5'-AAAWTTTT-3') binding transcription factor. RRPEs are commonly found 5' of genes required for ribosome biogenesis and growth in response to addition of glucose to quiescent cells. Stb3p represses a large set of growth genes under poor nutrient conditions or stress. Stb3p also associates with promoters of ribosomal proteins. Stb3p is restricted to the nucleus by PKA and TORC1 in quiescent cells and is released into the cytoplasm after glucose repletion. Under starvation conditions, Stb3p recruits the Rpd3L histone deacetylase complex to ribosomal protein promoters. The details regarding regulation of ribosomal protein and ribosome biogenesis genes remains somewhat enigmatic.
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).
