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.
- Summary
- Cyclin-dependent protein kinase (CDK) regulatory subunit; regulates cell cycle passage through START by regulating transcription at the G1/S phase transcription; regulates non-autophagic vacuole fusion; localizes to the nucleus

Complex
Macromolecular complex annotations are imported from the Complex Portal. These annotations have been derived from physical molecular interaction evidence extracted from the literature and cross-referenced in the entry, or by curator inference from information on homologs in closely related species or by inference from scientific background.
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; dominant hyperactive alleles result in decreased critical cell size at START, decreased duration of the G1 phase, increased alpha-factor resistance, transient pheromone-induced cell cycle arrest, reduced mating efficiency; null mutants have an increased critical cell size at START, increased duration of the G1 phase, elevated chromosome instability, and increased chronological lifespan; homozygous diploid nulls have an increased sporulation efficiency and enhanced pseudohyphal growth

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).
