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 has a growth defect, is heat sensitive, and displays decreased competitive fitness on both fermentative and respiratory growth media; null mutant has a decreased ability to use raffinose as carbon source; null mutant has a reduced ability to target Doa4p to the endosome, an inability to sort MVB cargo protein to the vacuole and a strong vacuolar fragmentation defect; null mutant has decreased resistance to ionic stress, cadmium and manganese treatment, oxidative stress, and desiccation; null mutant is defective in regulating intracellular pH and displays decreased resistance to acid pH; null mutant has decreased telomere length, reduced innate thermotolerance, and a decreased ability to form biofilms; null mutant displays increased accumulation of cadmium, calcium and alanine and decreased accumulation of glycogen; homozygous diploid null mutant has a sporulation defect; heterozygous null mutant 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).
