== Function ==
[https://www.uniprot.org/uniprot/VIRF1_HHV8P VIRF1_HHV8P] Plays a role in the inhibition of host innate response by repressing the expression of interferon-inducible genes and blocking host IRF1- and IRF3-mediated transcription. Blocks the interaction between host IRF3 and CREBBP. Regulates the host cellular metabolism by increasing glucose uptake, ATP production and lactate secretion through down-regulation of heterogeneous nuclear ribonuclear protein Q1/SYNCRIP. Mechanistically, induces ubiquitination and degradation of SYNCRIP through the ubiquitin-proteasome pathway by recruiting KLHL3/CUL3 ubiquitin ligase complex (PubMed:35538151). Disrupts host TP53 signaling pathway during viral infection by interacting with host USP7 and thereby decreasing the availability of USP7 for deubiquitinating and stabilizing TP53 (PubMed:26786098).<ref>PMID:11314014</ref> <ref>PMID:26786098</ref> <ref>PMID:35538151</ref> <ref>PMID:9365244</ref> <ref>PMID:9420276</ref>
