Transactivator (Tat) of bovine immunodeficiency virus (BIV) is a virus encoded regulatory protein, which activates gene expression directed by BIV long terminal repeat (LTR), and plays an important role in BIV replica...
Two promoters, LTR (long terminal repeat) and IP (internal promoter), exist in genomes of foamy viruses. Cell transfection and transient expression assay demonstrated that: the basal activity of BFV (bovine foamy viru...
