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
- Mannose-binding protein involved in flocculation via cell wall protein-carbohydrate interaction and co-flocculation with other yeasts; also involved in the cellular response to heat, hydrogen peroxide, and ethanol; localizes to the cell wall

Molecular Function
- Manually Curated
- enables D-mannose binding (IMP)
Biological Process
- Manually Curated
- involved in flocculation (IMP)
Cellular Component
- Manually Curated
- located in cell periphery (HDA)
- located in fungal-type cell wall (IDA)
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 mutation blocks flocculation while overexpression increases it; null mutant is sensitive to ethanol and oxidative stress, and shows reduced competitive fitness in minimal medium
Classical Genetics
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
- The flo1 null mutant is viable; the null mutant of paralog flo5 is viable; the flo1 flo5 double mutant has not been annotated for phenotype.

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.
