Although the mechanism by which bovine leukemia virus (BLV) induces neoplastic transformation of the host B cells is unknown, it is likely that critical interactions between cellular DNA-binding proteins and the virus are involved. We have used DNase I protection (footprinting) assays to construct a map of protein-DNA interactions on the 5' long terminal repeat of BLV. In addition to the three cyclic AMP response elements previously reported, we have also found an NF-kappa B binding site between -118 and -70 nucleotides upstream of the RNA start site. This site binds several members of the kappa B family of proteins, including
p49
, p50, and p65, in both footprint and electrophoretic mobility shift assays and functions as an enhancer element when inserted upstream of the
chloramphenicol acetyltransferase
gene. NF-kappa B may be a critical nuclear binding protein that regulates both viral replication and key cellular genes in BLV-infected B cells.
