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 heat and cold sensitive, has a decreased fermentative growth rate and a severe respiratory growth defect; null mutant displays increased sensitivity to ER-stress inducing agents (e.g. DTT, tunicamycin and beta-mercaptoethanol) and to cell wall stressors (e.g. caspofungin, congo red, caffeine, calcofluor white and zymolyase treatment); null mutant is sensitive to osmotic and dessication stress; null is sensitive to treatment with various metals, acid and alkaline pH, and killer toxin; null mutant displays decreased mitophagy, delayed pexophagy, and has a strain specific autophagy defect; null mutant has a reduced cell size in saturated culture and a decreased chronological lifespan; heterozygous null is haploinsufficient

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).
