This entry represents the C-terminal ancillary domain (AD) of Auxin Response Factor (ARF) transcription factors. ARFs are modular transcription factors consisting of three main regions: an N-terminal DNA-binding domain (DBD) which includes a B3 domain embedded within a dimerization domain (DD), followed by a middle region that determines transcriptional activity, and finally a C-terminal protein-protein interaction domain (PB1/III/IV). The ancillary domain represented by this entry forms a small five-stranded beta-barrel-like structure that tightly interacts with the dimerization domain.	Domain

This is a family of plant transcription factors with various roles in development, the aligned region corresponds the B3 DNA binding domain as described in [1] this domain is found in VP1/AB13 transcription factors [2]. Some proteins also have a second AP2 DNA binding domain Pfam:PF00847 such as RAV1 Swiss:Q9ZWM9 [1]. DNA binding activity was demonstrated by [3].	Domain
