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.


Summary
Subunit of the core mediator complex; functions as a RNA pol II coactivator involved in preinitiation complex assembly; binds TFIIE and TFIIH-class transcription factors; recruits Gcn4p to the transcriptional machinery; involved in regulation of transcription from RNA polymerase II promoters, positive regulation of invasive growth in response to glucose limitation, and regulation of core mediator complex localization to chromosomes in response to heat shock

Cellular Component

Manually Curated

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 Details

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 exhibits slow growth, slow respiratory growth, sensitivity to visible light-induced stress, increased resistance to MMS and to rapamycin, decreased oxidative stress resistance, decreased osmotic stress resistance, increased mitophagy, increased heat sensitivity, decreased competitive fitness, decreased resistance to cycloheximide, camptothecin, HU, acidic pH, fluconazole; overexpression slows growth
Interaction Details

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.

Summary
GAL11 (also called MED15) encodes a component of the tail module of the Mediator transcriptional regulation complex. The Mediator complex is highly conserved from yeast to human, and is a central player in the transcriptional regulation of protein-coding genes, being required for nearly all transcription by RNA polymerase II (RNAPII). Mediator bridges activators and the general transcription machinery. The core Mediator complex contains three distinct head, middle, and tail modules. Gal11p, Nut1p, Pgd1p, Med2p, and Sin4p are part of the tail module, which has a gene-selective, as opposed to a general, role in transcription, and is largely dedicated to the activation of genes involved in cellular responses to environmental signals. By interacting with activators, Mediator tail module subunits signal through the head and middle modules, which interact with general transcription factors and RNAPII subunits, to the basal transcription machinery to regulate transcription initiation. The tail module preferentially targets stress-regulated, TATA-containing, SAGA- and Swi/Snf-dependent genes, and may function along with specific chromatin regulators to provide a platform for preinitiation complex (PIC) formation at these highly regulated loci. Subunits of the Mediator tail module are also required for the activation of metabolic genes. Oleate-activated transcription factor Oaf1p interacts directly with Gal11p through the conserved KIX domain to regulate fatty acid metabolism. Gal11p regulates galactose and amino acid metabolism by directly interacting with transcriptional activators Gal4p and Gcn4p. Gal11p also binds directly the pleiotropic drug response transcription factor Pdr1p to influence regulation of genes involved in drug-efflux pumps.

Expression Details

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).
