功能: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. Plays also 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).

- Based on experimental data obtained from E7 proteins from the prototypical viral types 16, 18 and 11, we identified a couple of low pKa nucleophilic cysteines that can form a disulfide bridge upon the exposure to ROS and regulate the cytoplasm to nucleus transport PMID: 27863297
- E7 is major transforming oncoprotein of human papillomavirus 16 and serves as paradigmatic example of intrinsically disordered proteins due to its N-terminal disordered domain. Data suggest mutation of leucines in N-terminal intrinsically disordered domain of E7 leads to pronounced increase in both alpha-helix and beta-sheet structures; thus, E7 appears to exhibit local structural elements that oppose canonical folding. PMID: 28952717
- s observed thousands of unique HPV16 genomes; very few women shared the identical HPV16 sequence, however, E7 was devoid of variants in precancers/cancers compared to higher levels in the controls; this was confirmed in cancers from around the world.
