We have previously identified new binding sites for transcription factors downstream of the transcription start site ( nt 465 to 720 ): three AP-1 sites (I, II, and III), an AP3-like motif ( AP3-L ), a downstream binding factor (DBF) site , and juxtaposed Sp1 sites .
 ( protein: transcription factors, None) , ( DNA: juxtaposed Sp1 sites, None) , ( DNA: AP-1 sites, None) , ( DNA: AP3-L, None) , ( DNA: nt 465 to 720, None) , ( DNA: downstream binding factor (DBF) site, None) , ( DNA: AP3-like motif, None) , ( DNA: transcription start site, None)
