Probably acts as a transcriptional activator. Binds to the GCC-box pathogenesis-related promoter element. May be involved in the regulation of gene expression by stress factors and by components of stress signal transduction pathways (By similarity). Interacts with BTB/POZ-MATH proteins BPM1, BPM2, BPM3, BPM4, BPM5 and BPM6. Mostly expressed in roots and leaves. Also detected in flowers and stems. Belongs to the AP2/ERF transcription factor family. ERF subfamily.
