== Function == | |||
[https://www.uniprot.org/uniprot/VE7_HPV16 VE7_HPV16] Plays a role in viral genome replication by driving entry of quiescent cells into the cell cycle. Stimulation of progression from G1 to S phase allows the virus to efficiently use the cellular DNA replicating machinery to achieve viral genome replication. E7 protein has both transforming and trans-activating activities. Induces the disassembly of the E2F1 transcription factor from RB1, with subsequent transcriptional activation of E2F1-regulated S-phase genes. Interferes with host histone deacetylation mediated by HDAC1 and HDAC2, leading to transcription activation. Also plays a role in the inhibition of both antiviral and antiproliferative functions of host interferon alpha. Interaction with host TMEM173/STING impairs the ability of TMEM173/STING to sense cytosolic DNA and promote the production of type I interferon (IFN-alpha and IFN-beta).[HAMAP-Rule:MF_04004]<ref>PMID:11080488</ref> <ref>PMID:1316611</ref> <ref>PMID:2836062</ref> [https://www.uniprot.org/uniprot/A0A678ZGP6_HUMAN A0A678ZGP6_HUMAN] [https://www.uniprot.org/uniprot/B2MG_PONPY B2MG_PONPY] Component of the class I major histocompatibility complex (MHC).
