Study of the HIV-2 Env cytoplasmic tail variability and its impact on Tat, Rev and Nef.

Abstract excerpt

BACKGROUND: The HIV-2 env's 3' end encodes the cytoplasmic tail (CT) of the Env protein. This genomic region also encodes the rev, Tat and Nef protein in overlapping reading frames. We studied the variability in the CT coding region in 46 clinical specimens and in 2 reference strains by sequencing and by culturing. The aims were to analyse the variability of Env CT and the evolution of proteins expressed from...
