B3结构域
B3 DNA结合结构域(英語:)是一些转录因子中的高度保守的DNA结合结构域(DNA-binding domain,DBD)在超过40个物种(Pfam PF02362)中发现,与其它结构域一起(IPR003340)执行转录因子的功能。B3结构域的一级结构为100-120个氨基酸残基,二级结构为七个β折叠和两个α螺旋,三级结构为假棒状(pseudobarrel,Template:SCOP),从DNA结构的大沟处结合DNA分子[1]。

B3 蛋白家族
在拟南芥(Arabidopsis thaliana)中,有三个主要的转录因子家族带有B3结构域[2]:
- ARF(Auxin Response Factors)
- ABI3(ABscisic acid Insensitive3)
- RAV(Related to ABI3/VP1)
