CRYSTAL STRUCTURE OF THE HPV-18 E2 DNA-BINDING DOMAINCRYSTAL STRUCTURE OF THE HPV-18 E2 DNA-BINDING DOMAIN
Structural highlights
1f9f is a 4 chain structure with sequence from Human papillomavirus type 18. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
VE2_HPV18 E2 regulates viral transcription and DNA replication. It binds to the E2RE response element (5'-ACCNNNNNNGGT-3') present in multiple copies in the regulatory region. It can either activate or repress transcription depending on E2RE's position with regards to proximal promoter elements. Repression occurs by sterically hindering the assembly of the transcription initiation complex. The E1-E2 complex binds to the origin of DNA replication.
