Transcription factor that 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. Probably acts as a transcriptional activator (By similarity). Weakly expressed in roots. Induced by ethylene. 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 ethylene-response factor family. Class 1 subfamily.
