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 shows abnormal vacuolar morphology, respiration defects, decreased lifespan and competitive fitness, and is sensitive to dessication; homozygous diploid null is impaired in sporulation; overexpression slows growth

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.

- Summary
- CAT8 encodes a transcription factor that is a member of the C6 zinc finger class, containing a DNA binding domain also known as the Zn2Cys6 binuclear zinc cluster or zinc knuckle. In the absence of glucose, Cat8p binds to carbon source response elements (CSREs) in the promoters of its target genes to activate transcription. Regulatory targets of Cat8p include genes involved in gluconeogenesis and the glyoxylate cycle, such as FBP1, ICL1, and PCK1, and including the transcription factor SIP4. Cat8p is required for utilization of nonfermentable carbon sources. Along with Cat8p, the transcription factors Sip4p and Rds2p also contribute to regulation of genes involved in gluconeogenesis. All three factors bind to target sites with the same consensus sequence, although each has a preference for particular variants of the sequence, and they have overlapping regulatory roles. In the presence of glucose, CAT8 transcription is repressed by Mig1p. In the absence of glucose, CAT8 transcription is upregulated, and in addition, Cat8p is activated via phosphorylation, primarily by the Snf1p kinase.
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.
