Plant-specific B3-DNA binding domain
The plant-specific B3 DNA binding domain superfamily includes the well-characterized auxin response factor (ARF) and the LAV (Leafy cotyledon2 [LEC2]-Abscisic acid insensitive3 [ABI3]-VAL) families, as well as the RAV (Related to ABI3 and VP1) and REM (REproductive Meristem) families. LEC2 and ABI3 have been shown to be involved in seed development, while other members of the LAV family seem to have a more general role, being expressed in many organs during plant development. Members of the ARF family bind to the auxin response element and depending on presence of an activation or repression domain, they activate or repress transcription. RAV and REM families are less studied B3 protein famillies.
