Regulation of human cytomegalovirus US3 gene transcription by a cis-repressive sequence.

abstract：:The γ134.5 gene of herpes simplex virus 1 (HSV-1) encodes a virulence factor that promotes viral pathogenesis. Although it perturbs TANK-binding kinase 1 (TBK1) in the complex network of innate immune pathways, the underlying mechanism is obscure. Here we report that HSV-1 γ134.5 targets stimulator of interferon genes...
