Source Description
TAIREncodes a basic domain leucine zipper (bZip) transcription factor bZIP11. Translation is repressed by sucrose. Directly regulates gene expression of ASN1 and ProDH2, which are enzyme-coding genes involved in amino acid metabolism.
UniProtTranscription factor that binds to the DNA sequence 5'-ACTCAT-3' in target gene promoters. Promotes POX1/PRODH1 expression in response to hypoosmolarity stress (PubMed:15047879). Positively regulates the expression of ASN1 and POX2/PRODH2 genes, which are involved in amino acid metabolism (PubMed:18088315). Regulates several metabolic pathways such as myo-inositol, raffinose and trehalose. Regulates several trehalose metabolism genes, including TRE1, TPP5 and TPP6 (PubMed:21534971). Mediates recruitment of the histone acetylation machinery to activate auxin-induced transcription. Interacts with ADA2B adapter protein to promote ADA2B-mediated recruitment of SAGA-like histone acetyltransferase complexes to specific auxin-responsive genes (PubMed:24861440). {ECO:0000269|PubMed:15047879, ECO:0000269|PubMed:18088315, ECO:0000269|PubMed:21534971, ECO:0000269|PubMed:24861440}.

  1. bZIP11 target processes are identified using transiently increased nuclear bZIP11 levels and genome-wide expression analysis; the effect of bZIP11 on ASN1 and GBF6 are reported.
    [PMID: 18088315]
  2. The uORF2 element in the bZip11 mRNA encodes a sucrose control peptide that inhibits bZIP11 translation in response to high sucrose levels by stalling the ribosome on the mRNA.
    [PMID: 19403731]
  3. The bZIP11 induction leads to reduced contents of the prominent growth regulatory molecule trehalose 6-phosphate (T6P). The metabolic changes detected mimic in part those observed in carbon-starved plants.
    [PMID: 21534971]
  4. Arabidopsis bZIP11-related basic leucine zipper (bZIP) transcription factors interact via an amino-terminal activation domain with ADA2b adapter proteins to recruit the histone acetylation machinery to specific auxin-responsive genes.
