Protein
AT-hook motif nuclear-localized protein 25
Organism
Arabidopsis thaliana
Function
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.
