SIZ1 Antibody

1. Arabidopsis thaliana SIZ1 controls nuclear localization of Nitrate Reductases proteins, and ammonium negatively regulates their levels. PMID:29662028
2. SIZ1 suppresses an SNC1-dependent resistance response at both normal and high temperatures. At the same time, SIZ1 amplifies the dark and high temperature growth response, likely via COP1 and upstream of gene regulation by PIF4 and BRZ1. PMID:29357355
3. The SnRK1 complex is SUMOylated on multiple subunits and identify SIZ1 as the E3 Small Ubiquitin-like Modifier (SUMO) ligase responsible for this modification. PMID:26662259
4. regulates seed dormancy and germination PMID:27130140
5. SUMO-conjugated proteins accumulate in response to high doses of sugar in a SIZ1-dependent manner. PMID:26468507
6. The methylation level of the Arabidopsis genome, including transposons, was significantly lower in the siz1-2 mutant than in wild-type plants. CMT3 was sumoylated by the E3 ligase activity of AtSIZ1 through a direct interaction. PMID:26398805
7. negatively affects stomatal closure and drought tolerance through accumulation of salicylic acid PMID:22963672
8. This study establishes that the diverse properties characteristic of SIZ1 are associated with specific domains and that they can be separated. PMID:20404572
9. The AtSIZ1 mutation is correlated with an overall decrease in alternative respiration and with a low carbohydrate content to maintain the carbon to nitrogen ratio in siz1-2 mutants. PMID:22732219
10. SIZ1 sustains the stability and normal function of the mature female gametophyte which is necessary for pollen tube guidance. PMID:22253727
11. The expression and enzymatic activity of Cu/ZnSOD1 (CSD1) in shoots of the siz1 mutant under excess Cu, was examined. PMID:21897129
12. These data suggest that SIZ1-mediated sumoylation is involved specifically in copper homeostasis and tolerance in planta. PMID:21632972
13. AtSIZ1 positively controls nitrogen assimilation by promoting sumoylation of nitrate reductases in Arabidopsis. PMID:21772271
14. SIZ1 facilitates the auxin-regulated root architecture remodeling that occurs in response to Pi deficiency. PMID:21156857
15. The salicylic acid-accumulating mutant siz1 exhibits sensitivity to chilling and freezing conditions. PMID:19959255
16. These results indicate that SIZ1 regulates cell growth and plant development with regulation of salicylic acid accumulation. PMID:20007967
17. The various domains of SIZ1 make unique contributions to the plant's ability to cope with its environment. PMID:19837819
18. SIZ1 and sumoylation facilitate basal thermotolerance through processes that are salicylic acid independent. PMID:17041025
19. SIZ1 is required for salicylic acid and PAD4-mediated R gene signalling, which in turn confers innate immunity in Arabidopsis.[SIZ1] PMID:17163880
20. SIZ1 is a SUMO E3 ligase that facilitates conjugation of SUMO to protein substrates. PMID:17416732
21. SIZ1 regulates Arabidopsis growth and that this SUMO E3 ligase plays a role in drought stress response likely through the regulation of gene expression. PMID:17905899
22. Results suggest that SIZ1 is a floral repressor that not only represses the SA-dependent pathway, but also promotes FLC expression by repressing FLD activity through sumoylation, which is required for full FLC expression in a FRIGIDA background. PMID:18069938
