Target Background

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).

  7. 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
  8. 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
  9. Authors 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.

  14. the level of Cdc6 phosphorylation at serine 54 (S54P) was increased in E7-expressing cells. S54P was associated with an increase in the total amount of Cdc6 and chromatin-bound Cdc6.

  22. Results found that HPV16 E7 increases RARB mRNA and protein expression both in vitro and in the cervix of young K14E7 transgenic mice suggesting that RARB overexpression is part of the early molecular events induced by the E7 oncoprotein. PMID: 26173416
  23. E7 localised to the plasma membrane in cervical cancer cells. PMID: 26131956
  24. findings suggest that increased IL-17A expression by macrophages in E7-expressing skin exposed to DNCB promotes arginase-1 induction and contributes directly to the observed hyperinflammation. PMID: 25720383
