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
- Subunit of the MPS2-BBP1 spindle pole body anchor complex, which is involved in localization of the spindle pole body and spindle pole body duplication; localized to central plaque of the spindle pole body

Molecular Function
- Manually Curated
- enables structural molecule activity (IDA)
Biological Process
- Manually Curated
- involved in protein localization to spindle pole body (IMP)
- involved in spindle pole body duplication (IGI, IMP)
Cellular Component
- Manually Curated
- located in central plaque of spindle pole body (IDA)
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
- Essential gene; conditional mutant is heat sensitive, fails to form a bipolar spindle in mitosis due to the inability to assemble a nuclear inner plaque during SPB duplication; conditional mutant has an M phase delay, a chromosome segregation defect, and an inability to localize Mps2p to the new SPB duplication plaque and Cdc5p to the SPB; repressible mutant displays a budding defect, abnormal chitin deposition, and absence of a mitotic spindle; overexpression at high levels results in inviability, and at lower levels results in a strong growth defect, and an increase in ploidy; overexpression in a diploid results in the formation of asci containing internal asci

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.

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.
Literature
All manually curated literature for the specified gene, organized into topics according to their relevance to the gene (Primary Literature, Additional Literature, or Review). Click "Literature Details" to view all literature information for this locus, including shared literature between genes.
