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.

Histone demethylase specific for K36 tri- and dimethylated histone H3; independently functions as a transcription factor that represses the expression of genes involved in autophagy and DNA repair; involved in transcriptional elongation

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.

The rph1 null mutant is viable; the null mutant of paralog gis1 is viable; the rph1 gis1 double mutant displays a synthetic growth defect.

RPH1 encodes a transcription factor that is a member of the C2H2 zinc finger class. Rph1p and its paralog Gis1p act as both transcriptional activators and repressors for overlapping sets of target genes. They act predominantly as repressors during exponential growth. Rph1p and Gis1p repress transcription of PHR1, and this repression is inhibited in response to DNA damage. After the diauxic shift, Rph1p and Gis1p function predominantly as transcriptional activators of genes involved in glycerol and acetate metabolism and in survival during stationary phase. Rph1p binds to stress response elements (STREs) in the promoters of its target genes. In addition to its role as a transcription factor, Rph1p also functions as a histone demethylase, acting on residue K36 of histone H3 during transcription elongation. Rph1p carries the JmjN and JmjC domains characteristic of histone demethylases. GIS1, the paralog of RPH1, encodes a transcription factor whose histone demethylase activity is not confirmed.
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).
