To find genes that protect cells from apoptosis , we used an expression cloning strategy and identified BHRF1 , an Epstein-Barr virus ( EBV ) early-lytic-cycle protein with distant homology to Bcl-2 , as an anti- apoptosis protein .
 ( protein: Bcl-2, None) , ( protein: anti- apoptosis protein, None) , ( protein: BHRF1, None) , ( protein: Epstein-Barr virus ( EBV ) early-lytic-cycle protein, None)
