Structural highlights

2bop is a 2 chain structure. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

[VE2_BPV1] E2 regulates viral transcription and DNA replication. Binds to the E2RE response element (5'-ACCNNNNNNGGT-3') present in multiple copies in the regulatory region. 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.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

The dominant transcriptional regulator of the papillomaviruses, E2, binds to its specific DNA target through a previously unobserved dimeric antiparallel beta-barrel. The DNA is severely but smoothly bent over the barrel by the interaction of successive major grooves with a pair of symmetrically disposed alpha-helices. The specific interface is an 'interwoven' network of interactions where the identifying base pairs of the target contact more than one amino-acid side chain and the discriminating amino acids interact with more than one base pair.
