CC   -!- FUNCTION: Minor structural protein that acts as an endoribonuclease
CC       during lytic infection. Degrades host mRNAs in the cytoplasm by cutting
CC       them at preferred sites, including some in regions of translation
CC       initiation. Together with inhibition of host splicing by ICP27,
CC       contributes to an overall decrease in host protein synthesis. Also,
CC       after the onset of viral transcription, accelerates the turnover of
CC       viral mRNA, thereby facilitating the sequential expression of different
CC       classes of viral genes. Binds translation initiation factors eIF4H,
CC       eIF4AI, and eIF4AII, thereby may interact directly with the translation
CC       initiation complex and thus digest specifically mRNAs. Also impedes
CC       antigen presentation by major histocompatibility complex class I and
CC       class II molecules, inhibits secretion of cytokines that would
CC       otherwise recruit lymphocytes and neutrophils cells to the site of
CC       infection and blocks the activation of dendritic cells. Impedes the
CC       alpha/beta interferon-mediated response to infection (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with human EIF4H, EIF4A1 and EIF4A2; interaction
CC       with eIF4AI and EIF4A2 presumably allows Vhs protein to associate with
CC       the eIF4F cap-binding complex. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the herpesviridae VHS protein family.
CC       {ECO:0000305}.
