 116-217 8.85e-26

B3 DNA binding domain; Two DNA binding proteins, RAV1 and RAV2 from Arabidopsis thaliana contain two distinct amino acid sequence domains found only in higher plant species. The N-terminal regions of RAV1 and RAV2 are homologous to the AP2 DNA-binding domain (see ) present in a family of transcription factors, while the C-terminal region exhibits homology to the highly conserved C-terminal domain, designated B3, of VP1/ABI3 transcription factors. The AP2 and B3-like domains of RAV1 bind autonomously to the CAACA and CACCTG motifs, respectively, and together achieve a high affinity and specificity of binding. It has been suggested that the AP2 and B3-like domains of RAV1 are connected by a highly flexible structure enabling the two domains to bind to the CAACA and CACCTG motifs in various spacings and orientations.

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.
