== Function ==
[https://www.uniprot.org/uniprot/EAR_EBVA8 EAR_EBVA8] Prevents premature death of the host cell during virus production, which would otherwise reduce the amount of progeny virus. Acts as a host B-cell leukemia/lymphoma 2 (Bcl-2) homolog, and interacts with pro-apoptotic proteins to prevent mitochondria permeabilization, release of cytochrome c and subsequent apoptosis of the host cell (By similarity).

== Publication Abstract from PubMed ==
Epstein-Barr virus (EBV) is associated with human malignancies, especially those affecting the B cell compartment such as Burkitt lymphoma. The virally encoded homolog of the mammalian pro-survival protein Bcl-2, BHRF1 contributes to viral infectivity and lymphomagenesis. In addition to the pro-apoptotic BH3-only protein Bim, its key target in lymphoid cells, BHRF1 also binds a selective sub-set of pro-apoptotic proteins (Bid, Puma, Bak) expressed by host cells. A consequence of BHRF1 expression is marked resistance to a range of cytotoxic agents and in particular, we show that its expression renders a mouse model of Burkitt lymphoma untreatable. As current small organic antagonists of Bcl-2 do not target BHRF1, the structures of it in complex with Bim or Bak shown here will be useful to guide efforts to target BHRF1 in EBV-associated malignancies, which are usually associated with poor clinical outcomes.
