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. 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 increased unsaturated fatty acid accumulation and decreased resistance to aluminum and quinoxaline; in large-scale studies, null mutant displays altered amino acid metabolism, severe competitive fitness defects, haploinsufficiency, extensive metal sensitivities including aluminum, gadolinium, and gallium, and decreased resistance to various chemicals including DNA synthesis inhibitor hydroxyurea and protein synthesis inhibitor cycloheximide; null mutant also shows increased resistance to some antifungal compounds and DNA-damaging agent methyl methanesulfonate; the null mutant of paralog sso1 is viable; the sso2 sso1 double mutant displays a synthetic growth defect

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.
- Summary
- Sso2p interacts physically with proteins involved in organelle fusion; SSO2 interacts genetically with genes involved in transcription by RNA polymerase II

Regulation
The number of putative Regulators (genes that regulate it) and Targets (genes it regulates) for the given locus, based on experimental evidence. This evidence includes data generated through high-throughput techniques. Click "Regulation Details" to view all regulation annotations, shared GO enrichment among regulation Targets, and a regulator/target diagram for the locus.
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.
All Curated Literature
All manually curated literature for the specified gene, shown as a count of references by year of publication followed by the most recent papers. Click "Literature Details" or "See all" to view all literature information for this locus, organized into topics according to their relevance to the gene (Primary Literature, Additional Literature, or Review).
