Transcription factor that specifically binds AT-rich DNA sequences related to the nuclear matrix attachment regions (MARs) (By similarity). Binds the DNA sequence GNFEI (GA-negative feedback element I) in the GA3OX1 promoter. Binding to GNFEI sequence is required for GA-negative feedback regulation of GA3OX1. Homodimer. Interacts with AHL27 and AHL29. Expressed in seedlings, leaves, stems, floral tips and flowers. The PPC domain mediates interactions between AHL proteins. Truncated N-terminus. Truncated N-terminus.
