Summary
REA1 is located on the right arm of chromosome XII between SNR79 C/D box snoRNA and REX3 RNA exonuclease; at 14733 nucleotides, REA1 has the longest coding sequence in the genome, with 62 synonymous SNPs, 38 amino acid polymorphisms, and a 21-nucleotide in-frame deletion in Σ1278b near the C-terminal end at nucleotide 12906
Protein Details

Protein

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.


Summary
Midasin Rea1p is 4910 amino acids long, somewhat shorter-lived, low in abundance; abundance increases when treated with methyl methanesulfonate; contains 8 AAA ATPase domains, 4 AAA lid domains; phosphorylated on 32 residues, ubiquitinylated on 3 lysines; protein sequence is 4903 amino acids in Σ1278b due to 7-aa in-frame deletion near C-terminus

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
An ATPase involved in ATP-dependent remodeling of the pre-60S particle, regulating export from the nucleus; localizes to nucleoplasm

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
Essential gene; repressible alleles reveal defects in rRNA processing and ribosome biogenesis; reduction of function alleles cause slow growth, long telomeres, decreased competitive fitness; heterozygous null mutants show elevated global mutation frequency and genetic instability; conditional alleles increase heat sensitivity, cause defects in rRNA processing and ribosome biogenesis
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.
