Viral protein involved in inhibiting host transcription to ensure the shutoff of cellular proteins expression and give virus transcripts a competitive edge for access to the cellular translation machinery. Preventing the expression of host proteins is also a strategy to counteract the antiviral response. Inhibition of transcription can be performed by interfering with host RNA pol-II function or interfering with general transcription factors.

Viral protein involved in the disruption of the host transcriptional machinery. Viruses have evolved ways of interacting with the cellular preinitiation complex (PIC) to shutoff host transcription initiation. For example, the TATA binding protein and TFIIH are targeted by some viral proteins and thus cannot assemble properly to form a functional PIC.

Protein involved in the transfer of genetic information from DNA to messenger RNA (mRNA) by DNA-directed RNA polymerase. In the case of some RNA viruses, protein involved in the transfer of genetic information from RNA to messenger RNA (mRNA) by RNA-directed RNA polymerase.
