SNQ2 basal levels of expression are positively regulated by Pdr1p, Pdr3p, and Stb5p, through the binding of these transcription factors to pleiotropic drug response elements (PDREs) present in the SNQ2 promoter (7, 12, 13, and 14). SNQ2 expression is also drug-induced by Yrr1p (15, 16) and heat-shock-induced by the AP-1 transcription factors Yap1p and Cad1p (17).

Snq2p is a member of the ATP-binding cassette (ABC) family of proteins, a large group that are conserved from bacteria to humans (1, 4). Overexpression of the human ABC transporter ABCB1/MDR1 (OMIM) is a factor in tumor resistance to drug therapy, and deficient ABC transporter function has been implicated in other human diseases as well (reviewed in 4). S. cerevisiae ABC proteins are often used as a model to study the clinical problem of drug resistance in infectious disease and cancer as well as in pharmaceutical screens for novel drugs (18 and reviewed in 19).", "date_edited": "2011-01-13"}, "literature_overview": {"primary_count": 76, "additional_count": 142, "review_count": 38, "go_count": 6, "phenotype_count": 8, "disease_count": 0, "interaction_count": 46, "regulation_count": 16, "ptm_count": 12, "funComplement_count": 0, "htp_count": 33, "total_count": 327}, "disease_overview": {"manual_disease_terms": [], "htp_disease_terms": [], "computational_annotation_count": 0, "date_last_reviewed": null}, "ecnumbers": [], "URS_ID": null, "main_strain": "S288C", "regulation_overview": {"regulator_count": 17, "target_count": 0}, "reference_mapping": {"599472": 1, "588911": 2, "555750": 3, "593793": 4, "552527": 5, "587469": 6, "649272": 7, "524983": 8, "634111": 9, "639493": 10, "475668": 11, "642623": 12, "561386": 13, "641147": 14, "599254": 15, "562183": 16, "623357": 17, "501202": 18, "522903": 19}, "history": [{"category": "Name", "history_type": "LSP", "note": "Name: SNQ2", "date_created": "2000-05-19", "references": [{"id": 599472, "display_name": "Servos J, et al.

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.


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).
