BZIP68

Gene
BZIP68
Protein
bZIP transcription factor 68
Organism
Arabidopsis thaliana
Length
389 amino acids
Function
Transcriptional activator that binds to the G-box motif (5'-CACGTG-3') and other cis-acting elements with 5'-ACGT-3' core, such as Hex, C-box and as-1 motifs. Possesses high binding affinity to G-box, much lower affinity to Hex and C-box, and little affinity to as-1 element (PubMed:18315949). G-box and G-box-like motifs are cis-acting elements defined in promoters of certain plant genes which are regulated by such diverse stimuli as light-induction or hormone control (Probable). Binds to the G-box motif 5'-CACGTG-3' of LHCB2.4 (At3g27690) promoter. May act as transcriptional activator in light-regulated expression of LHCB2.4. Probably binds DNA as monomer. DNA-binding activity is redox-dependent (PubMed:22718771).
