Murine cytomegalovirus targets transcription factor ATF4 to exploit the unfolded-protein response.

abstract：:The product of the human cytomegalovirus (HCMV) UL71 gene is conserved throughout the herpesvirus family. During HCMV infection, protein pUL71 is required for efficient virion egress and is involved in the final steps of secondary envelopment leading to infectious viral particles. We found strong indications for oligo...
