Gene Ontology Details

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.

mRNA-binding translation repressor involved in mRNA catabolism and iron homeostasis; localizes to both nucleus and cytoplasm

Phenotype Details


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.

Non-essential gene; null grows slowly, shows small defect in vacuolar fragmentation, defect in endocytosis, increased resistance to MMS, increased replicative and chronological lifespans, decreased desiccation resistance, increased competitive fitness; overexpression slows growth, reduces resistance to hydroxyurea and fluconazole, increases invasive growth
Interaction Details


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.

Tis11p interacts physically with proteins involved in RNA catabolism; TIS11 interacts genetically with genes involved in transcription; the tis11 null mutant is viable; the null mutant of paralog cth1 is viable; the tis11 cth1 double mutant displays a phenotypic enhancement

TIS11 transcription is downregulated by Rim101p during mitosis; TIS11 promoter is bound by Met32p and Met4p; TIS11 promoter is bound by Bur6p, Gcn5p, Med6p, and Xbp1p in response to heat; TIS11 transcription is regulated by Opi1p, Pdr1p, Srb5p, and Stp1p; TIS11 transcription is regulated by Sfp1p in response to stress; TIS11 transcription is upregulated by Zap1p in response to zinc starvation
Expression Details


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).
