THE CRYSTAL STRUCTURE OF THE E2 DNA-BINDING DOMAIN FROM HUMAN PAPILLOMAVIRUS AT 2.4 ANGSTROMSTHE CRYSTAL STRUCTURE OF THE E2 DNA-BINDING DOMAIN FROM HUMAN PAPILLOMAVIRUS AT 2.4 ANGSTROMS
Structural highlights
1a7g is a 1 chain structure with sequence from Human papillomavirus 31. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
VE2_HPV31 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.
