CC -!- FUNCTION: Transcriptional activator that binds specifically to the DNA
CC sequence 5'-TGACG-3'. Recognizes ocs elements like the as-1 motif of
CC the cauliflower mosaic virus 35S promoter. Binding to the as-1-like cis
CC elements mediate auxin- and salicylic acid-inducible transcription.
CC Required to induce the systemic acquired resistance (SAR) via the
CC regulation of pathogenesis-related genes expression. Binding to the as-
CC 1 element of PR-1 promoter is salicylic acid-inducible and mediated by
CC NPR1. Could also bind to the C-boxes (5'-ATGACGTCAT-3') with high
CC affinity. {ECO:0000269|PubMed:12897257}.
CC -!- SUBUNIT: Binds DNA as a dimer. Interacts with NPR1, NPR3 and NPR4.
CC Interacts with GRXC7/ROXY1 and GRXC9/GRX480.
