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
