Erik Procko, Geoffrey Y. Berguig, Betty W. Shen, Yifan Song, more

Cell > 2014 > 157 > 7 > 1644-1656

Because apoptosis of infected cells can limit virus production and spread, some viruses have co-opted prosurvival genes from the host. This includes the Epstein-Barr virus (EBV) gene BHRF1, a homolog of human Bcl-2 proteins that block apoptosis and are associated with cancer. Computational design and experimental optimization were used to generate a novel protein called BINDI that binds BHRF1 with...
