STU1 / YBL034C Overview
- Standard Name
- STU1 1
- Systematic Name
- YBL034C
- SGD ID
- SGD:S000000130
- Feature Type
- ORF , Verified
- Description
- MT plus-end-tracking non-motor protein; binds MTs, stabilizes interpolar MT plus ends, facilitates spindle MT polymerization and produces an outward force on spindle poles; required for mitotic spindle integrity; binds detached kinetochores (KTs) and upon phosphorylation by Mps1p recruits Slk19p, promoting capture and clustering; regulates spindle stability; relocalizes to MTs when captured KTs reach a spindle pole; localizes to spindles, spindles poles, and detached KTs; human CLASP1/2 homolog 1 2 3 4 5 6

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
- Microtubule- and kinetochore-binding protein involved in mitotic spindle assembly and attachment of spindle microtubules to kinetochore; promotes recruitment of Slk19p to kinetochores to mediate clustering; localizes to polar microtubules and mitotic spindle midzone

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.
Classical Genetics
- repressible
- null
- conditional
- reduction of function
- null
- overexpression

Large-scale Survey
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.

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).
