Protein
TGACG-sequence-specific DNA-binding protein TGA-1A
Organism
Nicotiana tabacum
Function
Transcriptional activator that binds specifically to the DNA sequence 5'-TGACG-3'. Recognizes ocs elements like the as-1 motif of the cauliflower mosaic virus 35S promoter. Binding to the as-1-like cis elements mediate auxin- and salicylic acid-inducible transcription. Could also bind to the Hex-motif (5'-TGACGTGG-3') another cis-acting element found in plant histone promoters.
Similarity
Belongs to the bZIP family.
