The bovine leukemia virus X region encodes a trans-activator of its long terminal repeat

I Katoh et al. Jpn J Cancer Res. 1987 Feb.

Abstract

We constructed a fusion plasmid, pMX-I, by which the major open reading frame, X-I, of the bovine leukemia virus (BLV) X gene was expressed under control of the mouse metallothionein promoter. pMX-I was cotransfected into CV1 monkey kidney cells together with another construct containing the BLV long terminal repeat (LTR) linked to the chloramphenicol acetyltransferase (CAT) structural gene. The result of assay of CAT synthesis suggests that the X-I product functions as a trans-acting activation factor of the BLV LTR.
