“…Here, we describe the functions of Arabidopsis thaliana PUB19 (AtPUB19), which we demonstrated in an in vitro assay to encode a U-box type E3 ubiquitin ligase. AtPUB19 was up-regulated by drought, salt, cold, and abscisic acid (ABA). …”

“…Moreover, CDKG1-dependent phosphorylation of SINA2 positively affects its E3 ubiquitin ligase activity. CONCLUSIONS: Based on these results, we propose that CDKG1 modulates SINA2 ubiquitin ligase activity to regulate its effect on plant responses to ABA and osmotic stress. …”

“…In this study, we identified and characterized OsDIRP1 (Oryza sativa Drought-Induced RING Protein 1), a nuclear-localized putative RING E3 ubiquitin (Ub) ligase in rice (Oryza sativa L.). OsDIRP1 expression was induced by drought, high salinity, and abscisic acid (ABA) treatment, but not by low temperature (4°C) stress, suggesting that OsDIRP1 is differentially regulated by different abiotic stresses. …”
