Acts 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. Involved in disease resistance pathways. Induced by jasmonate (JA) and Alternaria brassicicola (locally and systemically). Ethylene induction is completely dependent on a functional ETHYLENE-INSENSITIVE2 (EIN2) while wounding induction does not require EIN2. Transcripts accumulate strongly in cycloheximide-treated plants, a protein synthesis inhibitor. Seems to not be influenced by exogenous abscisic acid (ABA), cold, heat, NaCl or drought stress. The AP2/ERF domain binds specifically to the 5'-GCCGCC-3' motif. The affinity of this binding is higher if the seventh amino-acid of this domain is basic (By similarity). Belongs to the AP2/ERF transcription factor family. ERF subfamily.
