Role of immunoproteasome catalytic subunits in the immune response to hepatitis B virus.

abstract：:The immediate-early 1 and 2 (IE1 and IE2, respectively) proteins of human cytomegalovirus are known transcription factors, which regulate the expression of viral and cellular genes. Transcriptional activation by IE2 is dependent on the presence of a TATA motif in target promoters, and IE2 can interact directly with th...
