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
Atg8 and Atg12 activating enzyme; involved in macroautophagy, cytoplasm-to-vacuole targeting (CVT) pathway, late nucleophagy, piecemeal microautophagy of nucleus, protein lipidation and mitochondrion degradation; localizes to the pre-autophagosomal structure (PAS) and mitochondrion

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; reduction of function mutant is unable to undergo autophagy and the CVT pathway; null mutant is unable to undergo late nucleophagy and pexophagy, and displays reduced mitophagy and micronucleophagy; null mutant has decreased viability during nitrogen starvation and abnormal nuclear morphology; null mutant is unable to localize Atg8p to the PAS; chronological lifespan is decreased in minimal medium but extended during growth in rich conditions; null mutant is defective in starvation-induced protein degradation; null mutant displays decreased glycogen accumulation during stationary phase; null mutant has decreased desiccation resistance, decreased resistance to zinc treatment and increased survival following a ramped heat stimulus; homozygous diploid null mutant is unable to sporulate; overexpression results in decreased filamentous growth
Disease Details

Disease

Disease Annotations consist of three mandatory components: a gene product, a term from the Disease Ontology (DO) controlled vocabulary and an evidence code. SGD provides manually curated DO Annotations derived from the literature. Click "Disease Details" to view all Disease information and evidence for this locus as well as diseases it shares with other genes.


Summary
Yeast ATG7 is homologous to human ATG7 and has been used to study distinct ATG7 variants in complex neurodevelopmental disorders with brain, muscle, and endocrine involvement

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.
