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 mutant has a large cell size with abnormally elongated bud, and an anaphase delay; null mutant is heat and cold sensitive, slow growing at permissive temperature and has competitive fitness defects; null mutant is sensitive to sterol biosynthesis inhibitors and membrane fluidizing agents, accumulating sterol precursors and monounsaturated fatty acids at reduced temperatures; null mutant is defective in the nuclear export of poly(A)+ mRNA, mislocalizes nuclear pore complex (NPC) cytoplasmic filament proteins and mRNA export factor, Dbp5p; null mutant has a vacuolar fragmentation deficiency, and nuclear morphology defects with abnormal nuclear envelope and NPC distribution; null mutant displays filamentous growth defects and is unable to undergo invasive growth; null mutant has decreased chronological lifespans, decreased acquired thermotolerance and does not accumulate trehalose after heat shock; null mutant is sensitive to metal treatment and antifungals
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.

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.
