a putative transcription factor , c/ebp , isolated from rat liver nuclei , has been shown to bind to at least two different sequence motifs : the ccaat promoter domain and a core sequence [ gtgg ( t/a ) ( t/a ) ( t/a ) g ] common to many viral enhancers , including simian virus 40 and human hepatitis b virus .
