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.

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.

- Summary
- GRR1/YJR090C is a non-essential gene; null mutants are viable, slow-growing, and associated with a range of mutant phenotypes that significantly impact cellular functions and overall fitness. Mutants lacking GRR1 exhibit decreased resistance to both acidic and alkaline pH levels, which may hinder their survival in varying environmental conditions. These mutants show an increased ability to form biofilms, which could affect their interactions with surfaces and other cells. The budding pattern in null mutants is abnormal, characterized by bipolar budding, and bud morphology is also disrupted, indicating potential issues with cell division. Competitive fitness is diminished, leading to reduced viability in resource-limited environments, while desiccation resistance is decreased, making them more vulnerable to dry conditions. The rate of fermentative growth is reduced, and these mutants also exhibit decreased resistance to freeze-thaw cycles. Invasive growth is increased, suggesting an enhanced ability to penetrate surfaces or tissues. Resistance to killer toxins is decreased, and lipid particle morphology is abnormal, which may impact cellular metabolism. Furthermore, oxidative stress resistance is diminished, and respiratory growth is absent, indicating a reliance on fermentation for energy production. UV resistance is also decreased, further underscoring their vulnerability to environmental stressors. Reduced function mutants show an increased rate of fermentative metabolism, suggesting a compensatory mechanism in response to the loss of function. However, when GRR1 is overexpressed, competitive fitness is again decreased, and UV resistance is diminished, indicating that excessive levels of the gene or gene product may also be detrimental.

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).
