Hepatitis B virus transcriptional activators: mechanisms and possible role in oncogenesis
1 May 1996
Abstract excerpt
The hepatitis B virus (HBV) genome encodes a 154 amino acid protein termed X (HBx, hepatitis B x protein), which is a promiscuous transcriptional activator of polymerase II and III promoters. HBx upregulates a wide range of cellular and viral genes and is thought to facilitate viral pregenome and mRNA transcription; however, its precise role in the viral replication cycle remains to be elucidated. The functional...
