| Locus name | AT2G23140 |
| Alias | PUB4 |
| Organism | Arabidopsis thaliana |
| Taxonomic identifier | [NCBI] |
| Function category | Protein degradation/modification:E3 ubiquitin ligase |
| Effect for Senescence | delay |
| Gene Description | PLANT U-BOX 4 (PUB4) encodes a functional ubiquitin-protein ligase. The gene is expressed in most plant tissues and the protein localizes to the nucleus. |
