DESCRIPTION

Also known as ARFA_ARATH, ARF1. Auxin response factors (ARFs) are transcriptional factors that bind specifically to the DNA sequence 5'-TGTCTC-3' found in the auxin-responsive promoter elements (AuxREs). Seems to act as transcriptional repressor. Formation of heterodimers with Aux/IAA proteins may alter their ability to modulate early auxin response genes expression. Promotes flowering, stamen development, floral organ abscission and fruit dehiscence. Acts as repressor of IAA2, IAA3 and IAA7. Homodimers and heterodimers. Interacts with the auxin-responsive proteins IAA12, IAA13, IAA17 and with ARF2.
