We also demonstrated that HBx regulates HIV-1 transcription through stimulating the binding of transcriptional regulatory proteins C/EBPß, CREB1, and CREB2 to HIV-1 LTR and that co-activator CBP is required for such regulation

The recruitment of these transcription factors to the STAR proximal promoter results in association of CBP and activation of RNA polymerase II leading to increased STAR transcription
