abstract：:ICP0, an alpha (immediate-early) protein of herpes simplex virus 1, performs at least two key functions. It blocks inhibition of viral-gene expression by interferon, a function dependent on the degradation of the ND10 components PML and SP100 by the ubiquitin ligase expressed by the RING finger (RF), and it blocks sil...
