May act as a transcriptional activator. Binds to the GCC-box pathogenesis-related promoter element. Involved in the regulation of gene expression by stress factors and by components of stress signal transduction pathways (By similarity). Weakly induced by Pseudomonas syringae tomato (avirulent avrRpt2 strain), but also by mock inoculation. Belongs to the AP2/ERF transcription factor family. ERF subfamily.
