FAP1 / YNL023C Overview


Standard Name
FAP1 1
Systematic Name
YNL023C
SGD ID
SGD:S000004968
Feature Type
ORF , Verified
Description
Cytoplasmic RING-finger E3 Ub-ligase and sensor of stalled ribosomes; binds to Fpr1p and Smu2p, and triggers K63-linked polyubiquitination of monoubiquitinated 40S subunit Rps3p, from decoding-defective ribosomes, followed by dissociation of the 80S ribosomes and non-functional rRNA decay (NRD) of 18S rRNA; confers rapamycin resistance by competing with rapamycin for Fpr1p binding; accumulates in the nucleus in rapamycin-treated cells; ortholog of D. melanogaster shuttle craft and human NFX1 1 2
Name Description
FKBP12-Associated Protein 1

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 displays chromosome instability, increased competitive fitness, small defect in vacuolar fragmentation, decreased utilization of glutamate as nitrogen source, decreased resistance to fluoride and to acids, increased accumulation of metals, decreased heat tolerance; overexpression increases resistance to rapamycin
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.
