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.

Sequence-specific DNA-binding transcription factor; involved in negative regulation of transcription meiotic cell cycle genes; also involved in positive regulation of transcription of mitotic cell cycle genes during G1/S transition; localized to nucleus

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.

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.

RME1 encodes a transcription factor that is a member of the C2H2 zinc finger class. In haploid cells, Rme1p prevents the initiation of meiosis by negatively regulating IME1, encoding a master activator of meiosis. Rme1p also promotes mitosis, by positive regulation of the G1 cyclin gene CLN2. In addition, Rme1p has a major role in promoting filamentous growth via activation of transcription of FLO11, encoding a cell surface adhesin. Rme1p binds to Rme1 Response Elements, RREs, in the promoters of its target genes. Rme1p was thought to function as both a transcriptional activator, usually when bound close to its target promoter, and as a transcriptional repressor, when bound at a distance from its target gene. However, recent evidence suggests that Rme1p is always a transcriptional activator. Repression of IME1 transcription is accomplished by activation of transcription of a long noncoding RNA, IRT1, that overlaps the IME1 gene. Transcription of IRT1 recruits histone deacetylases to the IME1 gene and induces the formation of repressive chromatin across the region. By analogy, the repressive action of Rme1p at sites distant from the repressed target is now suggested to be caused by activation of noncoding transcription and subsequent chromatin repression. In diploids, transcription of RME1 is repressed by MATa1p-MATalpha2p repressor, causing the IRT1 ncRNA not to be transcribed and thereby allowing IME1 to be transcribed and meiosis to occur.
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).
