Post-translational modifications of proteins by addition of ubiquitin can regulate protein degradation and localization, protein-protein interactions and transcriptional activation. In the ubiquitylation system, substrate specificity is primarily determined by the E2 ubiquitin-conjugating enzyme (UBC) and the E3 ubiquitin ligase. The Arabidopsis thaliana genome contains 37 genes encoding UBC homologs. However, the biological functions of these genes remain largely uncharacterized. Here, we… CONTINUE READING
