Sequence Details


The S. cerevisiae Reference Genome sequence is derived from laboratory strain S288C. Download DNA or protein sequence, view genomic context and coordinates. Click "Sequence Details" to view all sequence information for this locus, including that for other strains.

VPS1 is located on the right arm of Chromosome XI between the centromere and PAP1 poly(A) polymerase; coding sequence is 2115 nucleotides long with 11 SNPs, 9 of which are silent, 1 of which produces a K/Q polymorphism at residue 141, and 1 of which leads to a Q/H polymorphism at residue 254
Protein Details


Basic sequence-derived (length, molecular weight, isoelectric point) and experimentally-determined (median abundance, median absolute deviation) protein information. Click "Protein Details" for further information about the protein such as half-life, abundance, domains, domains shared with other proteins, protein sequence retrieval for various strains, physico-chemical properties, protein modification sites, and external identifiers for the protein.

Vps1p is 704 amino acids long with 6 dynamin signature domains, a GTPase domain near N-terminus, a central stalk, and a GTPase effector domain (GED) near C-terminus; shares domains with other proteins involved in mitochondrion organization; undergoes various post-translational modifications, including acetylation, phosphorylation, and ubiquitinylation at 15 residues

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.

GTPase involved in vacuolar protein sorting, protein retention in Golgi apparatus, peroxisome organization and fission, endocytosis, and actin cytoskeleton organization; localizes to the vacuole membrane, late endosome, peroxisome, and actin cortical patch; necessary for efficient trafficking of CoQ6 to mitochondria

Phenotype Details


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.

Non-essential gene; null mutant is defective in vacuolar protein sorting, resulting in decreased processing, missorting, and secretion of hydrolases; null mutant displays decreased endocytosis, a fragmented vacuolar morphology, fewer but enlarged peroxisomes and an altered endocytic vesicle distribution; null mutant is temperature sensitive and exhibits decreased ionic, oxidative and hyperosmotic stress resistance; null mutant has a respiratory growth defect, a reduced rate of nitrogen utilization and increased starvation induced mitophagy
Disease Details


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.

Yeast VPS1 is homologous to human DYNAMIN1 (DNM1) and has been used to study mutations found in patients with epileptic encephalopathy; yeast VPS1 is also homologous to human DYNAMIN2 (DNM2) and has been used to study mutations found in patients with microcytic anemia, centronuclear myopathy, Charcot-Marie-Tooth disease, and lethal congenital contracture syndrome
Interaction Details


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.

Regulation Details


The number of putative Regulators (genes that regulate it) and Targets (genes it regulates) for the given locus, based on experimental evidence. This evidence includes data generated through high-throughput techniques.

Expression Details


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).
