Abstract

Two regions of the Epstein-Barr virus BZLF1 trans-activator protein have sequence similarity to the c-fos protein. Part of the similarity corresponds to the region of c-fos which is similar to the DNA binding domain of c-jun and GCN-4. The structure of the exon which contains this region in c-fos and BZLF1 is also highly conserved between the two genes. Complete BZLF1 protein and a C terminal fragment were prepared either as purified fusion proteins or by in vitro translation from a BZLF1 cDNA. Gel retardation and DNase footprinting assays using these proteins show that BZLF1 is a sequence specific DNA binding protein capable of binding to a target sequence which contains a consensus AP-1 site.
