Curated mutant alleles for the specified gene, listed alphabetically. Click on the allele name to open the allele page. Click "SGD search" to view all alleles in search results.
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
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
Functional Networks display how gene products work together in biological systems. The Shared Annotations
network shows genes with similar GO annotations, suggesting functional relationships. GO-CAMs (Gene
Ontology Causal Activity Models) are manually curated pathway models that illustrate how molecular
activities of multiple gene products connect through causal relationships to carry out biological
processes. GO-CAMs integrate Molecular Function, Biological Process, and Cellular Component information
into unified pathway representations based on published experimental evidence. Click "View GO-CAM at Gene
Ontology" to explore the interactive model at AmiGO.
Click on a gene or Biological Process GO term name to go to its specific page within SGD; drag any of the gene or GO
term name objects around within the visualization for easier viewing; click “Reset” to automatically redraw the
diagram; filter the genes that share GO Biological Process terms with the given gene by the number of terms they
share by clicking anywhere on the slider bar or dragging the tab to the desired filter number.
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 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 number of putative Regulators (genes that regulate it) and Targets (genes it regulates) for the

high-throughput techniques. Click "Regulation Details" to view all regulation annotations, shared GO

Summary
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 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). Click "Expression Details" to view all expression annotations and
details for this locus, including a visualization of genes that share a similar expression pattern.
