UBA1 ubiquitin-activating enzyme 1 [Arabidopsis thaliana (thale cress)] - Gene

Summary

Official Symbol: UBA1
Official Full Name: ubiquitin-activating enzyme 1
Primary source: TAIR:AT2G30110
Locus tag: AT2G30110
See related: Araport:AT2G30110
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: ATUBA1; MODIFIER OF SNC1 5; MOS5; T27E13.15; T27E13_15; ubiquitin-activating enzyme 1
Summary: Encodes a ubiquitin-activating enzyme (E1), involved in the first step in conjugating multiple ubiquitins to proteins targeted for degradation. Gene is expressed in most tissues examined. Mutant is able to revert the constitutive defense responses phenotype of snc1, which indicates the gene is involved in defense response. It also indicates that ubiquitination plays a role in plant defense signalling.
