[[https://www.uniprot.org/uniprot/TFB1_YEAST TFB1_YEAST]] Acts as component of the general transcription and DNA repair factor IIH (TFIIH) core, which is essential for both basal and activated transcription, and is involved in nucleotide excision repair (NER) of damaged DNA. TFIIH has CTD kinase and DNA-dependent ATPase activity, and is essential for polymerase II transcription in vitro.<ref>PMID:7961739</ref> <ref>PMID:8631896</ref> [[https://www.uniprot.org/uniprot/VP16_HHV1F VP16_HHV1F]] Transcriptional activator of immediate-early (IE) gene products (alpha genes). Acts as a key activator of lytic infection by initiating the lytic program through the assembly of the transcriptional regulatory VP16-induced complex composed of VP16 and two cellular factors, HCFC1 and POU2F 1. VP16-induced complex represents a regulatory switch: when it is on, it promotes IE-gene expression and thus lytic infection, and when it is off, it limits IE-gene transcription favoring latent infection (By similarity).  May play a role in the aggregation of tegument proteins around nucleocapsids during virus morphogenesis.
