[ubiquitin-conjugating enzyme E2]-S-ubiquitin-L-cysteine + [transcription factor WRKY53]-L-lysine UPL5 is able to use the WRKY53 protein as a substrate for polyubiquitination in an in vitro system, and induction of UPL5 expression by an ethanol-inducible system in upl5 plants leads to degradation of the WRKY53 protein Arabidopsis thaliana [ubiquitin-conjugating enzyme E2D3]-L-cysteine + [transcription factor WRKY53]-N6-ubiquitinyl-L-lysine

General Information

General Information Comment Organism
physiological function isoform UPL5 T-DNA insertion lines show the same senescence phenotype as transcription factor WRKY53 over-expressers. Over-expression of WRKY53 in the upl5 background enhances the accelerated senescence phenotype of WRKY53 over-expressers Arabidopsis thaliana
