Human herpes viruses cause an array of illnesses ranging from cancers for Epstein?Barr virus and Kaposi?s sarcoma-associated herpes virus, to painful skin lesions, and more rarely, keratitis and encephalitis for HSV. All herpes viruses encode a multifunctional protein, typified by HSV ICP27, which plays essential roles in viral infection. ICP27 functions in all stages of mRNA biogenesis from transcription, RNA processing and export through to translation. ICP27 has also been implicated in nuclear protein quality control, cell cycle control, activation of stress signaling pathways and prevention of apoptosis. ICP27 interacts with many proteins and it binds RNA. This article focuses on how ICP27 performs its many roles and highlights similarities with its homologs, which could be targets for antiviral intervention.
