Epstein-Barr virus BZLF1 trans activator induces the promoter of a cellular cognate gene, c-fos.

Abstract

The Epstein-Barr virus BZLF1 gene product ZEBRA is a DNA-binding protein that is partially homologous to c-Fos, binds specifically to AP-1 sites, and can induce the lytic cycle in latently infected B lymphocytes. Induction of the viral lytic cycle can also be achieved by treatment with the phorbol ester 12-O-tetrade-canoylphorbol-13-acetate, a reagent which activates gene expression in part through AP-1 (Jun/Fos). In this article the interrelationship between ZEBRA and AP-1 is extended by the demonstration that ZEBRA can induce c-Fos expression through AP-1 and "AP-1-like" sites present in the c-fos promoter. Induction of c-Fos may be necessary for the expression of other viral lytic genes and perhaps cellular genes whose products are required for viral replication.
