The Early Restricted protein (Ea-R) of Epstein-Bar Virus is encoded by the viral BHFR1 gene. Ea-R is a 17 kDa protein (p17) with protein kinase activity. Ea-R-p17 is a functional homologue of the anti-apoptotic oncoprotein bcl-2, which is expressed during the switch from latency to lytic replication and may be involved in proliferation of EBV infected cells. However, Ea-R-p17 does not appear to be essential for virus replication or transformation of B cells in vitro.
