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. Ethylene induction is completely dependent on a functional ETHYLENE-INSENSITIVE2 (EIN2). Wounding as well as cold stress induction does not require EIN2. Transcripts accumulate strongly in cycloheximide-treated plants, a protein synthesis inhibitor. Seems to not be influenced by jasmonate, Alternaria brassicicola, 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.
