- Description
-
Basic leucine zipper (bZIP) transcription factor; required for oxidative stress tolerance; activated by H2O2 through the multistep formation of disulfide bonds and transit from the cytoplasm to the nucleus; Yap1p is degraded in the nucleus after the oxidative stress has passed; mediates resistance to cadmium; relative distribution to the nucleus increases upon DNA replication stress; YAP1 has a paralog, CAD1, that arose from the whole genome duplication

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.

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; null mutant show increased mutation frequency, decreased lifespan, decreased ethanol tolerance, decreased resistance to dessication, alkaline pH, resveratrol, oxidizing and reducing agents, carcinogens, antifungals, alkylating agents, metals, DNA metabolism inhibitors, protein and sterol synthesis inhibitors, and TOR inhibitor rapamycin; overexpression increases filamentous growth in Sigma1278b, interferes with cell cycle progression in S288C, and confers resistance to many of the aforementioned chemicals

Interaction Details
Interaction
Interaction annotations are curated by BioGRID and include physical

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.

- Summary
- YAP1 encodes an AP-1 type transcription factor which contains a basic leucine zipper domain (bZIP), and binds to a consensus Yap1p recognition element (YRE; 5'-TT/GAC/GTC/AA-3'). Yap1p is a key player in the cellular response to oxidative stress and xenobiotic insults, including drugs and heavy metals. The leader sequence of the YAP1 mRNA contains an upstream open reading frame (uORF), that allows leaky ribosomal scanning and reinitiation to the main ORF. Activation of Yap1p occurs in response to oxidants, particularly hydrogen peroxide. The activity of Yap1p is mainly regulated at the level of its export from the nucleus. Under normal conditions Yap1p is freely distributed between cytoplasm and nucleus, but mostly it is localized in the cytosol due to its active export from the nucleus by Crm1p, which binds a nuclear export signal (NES) in the C-terminal cysteine-rich domain (CRD) of Yap1p. Yap1p is activated by glutathione (GSH) peroxidase Hyr1p, which induces a conformational change and masks the NES contained in the C-terminal CRD, thereby inhibiting Yap1p-Crm1p bond formation. Once back in the nucleus, Yap1p initiates the transcription of specific genes by binding to the YREs contained in their promoter sequences. Yap1p promotes the transcription of several genes encoding antioxidants or antioxidant-associated molecules, such as those involved in the thioredoxin (TRX) and GSH systems, including AHP1, TRR1, TRX2, TSA1, GPX2, GSH1, GSH2, GLR1, SOD1, and SOD2. Yap1p can also be activated in response to diamide, and regulates the response to cadmium by upregulating transcription of transporter YCF1. Other target genes encoding transporters include ATR1 and FLR1.

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.
