tokens: It contains binding sites for several transcription factors , for example : ( i ) a well characterized binding site for rel / NF-kappaB transcription factors in its 3 ' - end ( the H2TF1 or kappaB1 element ) , ( ii ) a second kappaB site ( the kappaB2 element ) , which is located immediately adjacent 5 ' to the H2TF1 element and which is recognized by p65 / relA in the human HLA system , and ( iii ) an AP-1 / ATF recognition sequence in the 5 ' end ( EnA-TRE ) .
