== Function == | |||
[https://www.uniprot.org/uniprot/ICP4_HHV11 ICP4_HHV11] Plays an essential role in the regulation of viral gene expression by both activating and repressing host RNA polymerase II-mediated transcription. Binds with high affinity to the sequence 5'-ATCGTC-3'. Activates transcription by recruiting a form of the host TFIID to promoters and stabilizing the pre-initiation complex formation. Negatively regulates its own transcription. This immediate early (IE) protein is absolutely necessary for the transition from IE transcription to later viral gene transcription.<ref>PMID:18094162</ref> <ref>PMID:18216093</ref> <ref>PMID:1846804</ref> <ref>PMID:22496239</ref> <ref>PMID:23135715</ref> <ref>PMID:24147125</ref> <ref>PMID:8649420</ref> | |||
