In particular, naturally occurring sequence variation impacted transcription factor binding to an activating transcription factor/ cAMP response element binding ( ATF/CREB ) binding site (located between the LEF-1 and distal NF-kappaB transcription factor binding sites ) that we identified in previous studies of the HIV-1 LTR .
 protein: ATF/CREB; DNA: LTR; protein: LEF-1; protein: activating transcription factor/ cAMP response element binding; DNA: HIV-1 LTR; protein: transcription factor; DNA: activating transcription factor/ cAMP response element binding ( ATF/CREB ) binding site; protein: NF-kappaB
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2". 
Option: cell line, protein, RNA, DNA, cell type
