The "perfect palindrome 5'-GCCACGTGGC-3' which is also known as the G-box motif."
"TAF-1 can bind to the G-box and related motifs and that it functions as a transcription activator."
"A G-box-related motif, containing the core sequence CACGTG is also present in the 5' regions of two other classes of light-responsive genes".
