E7 - Protein E7 - Human papillomavirus type 16

Functionⁱ

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).UniRule annotation3 Publications

Miscellaneous

HPV16, in comparison to HPV types 6 and 11, is more often associated with malignant genital cancers in humans.

Interactionⁱ

Subunit structureⁱ

Homodimer (PubMed:11123931). Homooligomer (PubMed:15035602). Interacts with host RB1; this interaction induces dissociation of RB1-E2F1 complex thereby disrupting RB1 activity (PubMed:1316611). Interacts with host EP300; this interaction represses EP300 transcriptional activity (PubMed:12970734). Forms a complex with CHD4 and HDAC1, thereby altering the action of host histone deacetylation. A similar complex involving E7, CHD4 and HDAC2 may also form (PubMed:10228159). Interacts with protein E2; this interaction inhibits E7 oncogenic activity (PubMed:16439535).UniRule annotation6 Publications
