HY5 Antibody

1. Results suggest that light increases the endoplasmic reticulum stress sensitivity of plants and ELONGATED HYPOCOTYL 5, a positive regulator of light signaling, negatively regulates unfolded protein response gene expression in plant cells. PMID: 28167764

3. Prefoldins Negatively Regulate Cold Acclimation in Arabidopsis thaliana by Promoting Nuclear Proteasome-Mediated HY5 Degradation PMID: 28412546
4. BBX21 binds to the T/G-box in the HY5 promoter and directly activates HY5 expression in the light. PMID: 27325768
5. Arabidopsis ELONGATED HYPOCOTYL5 (HY5) is a shoot-to-root mobile signal that mediates light promotion of root growth and nitrate uptake. Shoot-derived HY5 auto-activates root HY5 and also promotes root nitrate uptake by activating NRT2.1, a gene encoding a high-affinity nitrate transporter. PMID: 26877080

8. Compromised activity of HY5 may have been mainly responsible for the partial reversal of the det1 phenotype in ted3 det1. PMID: 25248106
9. Ultraviolet-B causes unilateral accumulation of HY5, which then, in the end, leads to bending toward the light. PMID: 25096978
10. Data indicate that the bZIP transcription factor ELONGATED HYPOCOTYL5 (HY5) is enriched at target promoters in response to UV-B in a UV RESISTANCE LOCUS8 (UVR8) photoreceptor-dependent manner. PMID: 25351492
11. by directly targeting a common promoter cis-element (G-box), HY5 and PIFs form a dynamic activation-suppression transcriptional module responsive to light and temperature cues. PMID: 24922306
12. our investigation demonstrates that the COP1-HY5 complex is a novel integrator that plays an essential role in ethylene-promoted hypocotyl growth in the light PMID: 24348273
13. A possible interplay between PFT1 and another transcription factor, HY5, may regulate induction of APS reductase expression by light. PMID: 24583010
14. HY5 transmits phyA signals through an FHY1/FHL-independent pathway but it may also modulate FHY1/FHL signal through its interaction with HFR1 and LAF1. PMID: 23503597
15. Bifurcate regulation of anthocyanin biosynthesis by HY5 via transcriptional activation of PAP1. PMID: 23583450
16. The HY5-AtERF11 regulon is a key factor modulating abscisic acid-regulated ethylene biosynthesis. PMID: 21645149
17. HSP90 proteins respond to the tetrapyrrole-mediated plastid signal to control expression of photosynthesis-associated nuclear genes PMID: 22201048
18. HY5 and BBX24 act antagonistically in UV-B response. PMID: 22410790
19. HY5 binds to over 9000 genes, detectably affecting the expression of over 1100 genes, either positively or negatively. HY5 indirectly regulate many other genes through sub-networks mediated by other regulators. PMID: 21265889
20. HY5 represses the expression of PKS4 and auxin-related genes. PMID: 21848684
21. The genetic interaction between HY5 and FRY1 indicates that HY5 and FRY1 may act in overlapping pathways that mediate light signaling and lateral root development. PMID: 21301222
22. HY5 directly binds to C/G-box and G-box in the HTL promoter and regulates the expression of HTL. PMID: 20864454
23. Data show that HY5 plays a role in negative feedback regulation of phyA signaling by attenuating FHY3/FAR1-activated FHY1/FHL expression, providing a mechanism for fine-tuning phyA signaling homeostasis. PMID: 21097709
24. Data show that phosphorylation-mimicking serine substitutions strongly interfere with the DNA binding of two prototypical Arabidopsis bZIPs, namely AtZIP63 and HY5. PMID: 20047775
25. Det1 esp1 spa1 double mutant showed higher HY5 protein levels than either single mutant or the wild type. PMID: 20041285
26. HY5 is required for the transcriptional activation of the PFG1/MYB12 and PFG3/MYB111 genes under UV-B and visible light. PMID: 19895401
27. the first structural and biophysical characterization of HY5 is reported here. PMID: 17001643
28. HY5 is a high hierarchical regulator of the transcriptional cascades for photomorphogenesis. PMID: 17337630

30. Gibberellins signaling regulates protein stability of HY5, and the activity of PIF3. PMID: 18053005
31. Data show that at part of the remodeling of light signaling networks involves converting HY5, a positive regulator of PhANGs, into a negative regulator of PhANGs. PMID: 18065688
32. Arabidopsis HY5 functions as a novel DNA-binding tag (DBtag) for proteins. We also demonstrate that the DBtagged proteins could be immobilized and purified on a newly designed agarose/DNA microplate PMID: 18082144
