Description
RNA-binding protein; promotes transcription elongation and regulates termination; binds eIF4G to repress translation initiation; role in nuclear export of poly(A) mRNA and in pre-mRNA splicing; links chromatin modification to mRNA processing; prevents R-loop-mediated genome instability and replication stress; binds TERRA and stabilizes R-loops at short telomeres; phosphorylation by Sky1p promotes shuttling and mRNA dissociation; protein abundance increases in response to DNA replication stress 2 3 4 5 6 7 8 9 10 11 12

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
RNA-binding protein involved in pre-mRNA splicing and mRNA export from the nucleus; regulates RNA pol II transcription elongation and termination; implicated in translation termination and repression of translational initiation; shuttles between the cytoplasm and nucleus

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 in S288C, reported essential in Sigma1278b; null mutant is sensitive to elevated temperatures, metals and multiple drugs, including rapamycin, paromomycin, tacrolimus; in systematic studies homozygous null mutant diploid shows slow growth, decreased fermentative growth, inositol auxotrophy, decreased innate thermotolerance, abnormal budding pattern and elevated sensitivity to multiple drugs, including doxorubicin, echinocandin, fenpropimorph, hygromycin B
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. Click "Interaction Details" to view all interaction annotations and evidence for this locus, including an interaction visualization.

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).
