• PubMed Abstract: 
  

The three-dimensional structure of BHRF1, the Bcl-2 homolog from Epstein-Barr virus (EBV), has been determined by NMR spectroscopy. Although the overall structure is similar to other Bcl-2 family members, there are important structural differences. Unlike some of the other Bcl-2 family members, BHRF1 does not contain the prominent hydrophobic groove that mediates binding to pro-apoptotic family members. In addition, in contrast to the anti-apoptotic Bcl-2 proteins, BHRF1 does not bind tightly to peptides derived from the pro-apoptotic proteins Bak, Bax, Bik, and Bad. The lack of an exposed, pre-formed binding groove in BHRF1 and the lack of significant binding to peptides derived from pro-apoptotic family members that bind to other anti-apoptotic family members, suggest that the mechanism of the BHRF1 anti-apoptotic activity does not parallel that of cellular Bcl-x(L) or Bcl-2.
