Keyword - Inhibition of eukaryotic host transcription initiation by virus (KW-1111)

Keywords navigation

Broader

Definition

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.
