Arabidopsis thaliana BBR/BPC Family

Description

Santi et al. 2003: The barley b recombinant (BBR) protein binds specifically to the (GA/TC)8 repeat. BBR is nuclear targeted and is a characterized nuclear localization signal (NLS) sequence, a DNA-binding domain extended up to 90 aa at the C-terminus and a putative N-terminal activation domain. The corresponding gene has no introns and is ubiquitously expressed in barley tissues. In co-transfection experiments, BBR activates (GA/TC)8-containing promoters, and its overexpression in tobacco leads to a pronounced leaf shape modification. BBR has properties of a GAGA-binding factor, but the corresponding gene has no sequence homology to Trl and Psq of Drosophila, which encode functionally analogous proteins.
