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
Protein serine/threonine phosphatase involved in the inactivation of MAPK activity involved in osmolarity sensing and associated with cell wall integrity; also implicated in pheromone-dependent signal transduction, mitochondrion inheritance, and tRNA splicing via endonucleolytic cleavage and ligation; localizes to the nucleus and cytoplasm

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
PTC1/YDL006W is a non-essential gene; null mutants are viable but exhibit a range of phenotypic changes including decreased alkaline pH resistance, increased autophagy, auxotrophy, abnormal budding pattern, arrested cell cycle progression in the G1 phase, decreased competitive fitness, decreased cytokinesis, abnormal endoplasmic reticulum morphology, increased heat sensitivity, decreased ionic stress resistance, increased killer toxin resistance, abnormal lipid particle morphology, decreased metal resistance, abnormal mitochondrial distribution and morphology, decreased oxidative stress resistance, abnormal protein/peptide distribution and modification, decreased replicative lifespan, decreased resistance to enzymatic treatment, decreased respiratory growth rate, decreased small molecule transport, decreased sporulation, decreased telomere length, decreased toxin resistance, decreased utilization of carbon sources, abnormal vacuolar morphology, and decreased vegetative growth rate.
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). Click "Expression Details" to view all expression annotations and details for this locus, including a visualization of genes that share a similar expression pattern.
