NCBI Protein Information
bZIP transcription factor family protein
NCBI Summary
Transcription factor of the B-ZIP family that has high affinity for C-box motifs. Interacts with NPR1 and may regulate PR gene expression. Phosphorylated by a CK2-like protein in vitro. Phosphorylation is enhanced by salicylic acid treatment.

UniProt Comments
Transcriptional activator that binds specifically to the DNA sequence 5'-TGACG-3'. Recognizes ocs elements like the as-1 motif of the cauliflower mosaic virus 35S promoter. Binding to the as-1-like cis elements mediate auxin- and salicylic acid-inducible transcription. Required to induce the systemic acquired resistance (SAR) via the regulation of pathogenesis-related genes expression. Binding to the as-1 element of PR-1 promoter is salicylic acid-inducible and mediated by NPR1. Could also bind to the C-boxes (5'-ATGACGTCAT-3') with high affinity.
