Abstract

We constructed a series of deletion mutants of feline immunodeficiency virus (FIV) long terminal repeat (LTR) to identify the regions that regulate gene expression and are responsive to trans-activation of FIV LTR by feline herpes-virus type 1 (FHV-1). We demonstrated that sequences between -124 and -79, and between -21 and -32 (relative to the cap site) are essential for gene expression of FIV in Felis catus whole fetus 4 (fcwf-4) cells. Further, we demonstrated that the sequence between -63 and -23 responds to trans-activation of FIV LTR by FHV-1 in fcwf-4 cells.
