Abstract Background The Env glycoproteins of retroviruses play an important role in the initial steps of infection involving the binding to cell surface receptors and entry by membrane fusion. The Env glycoprotein also plays an important role in viral assembly at a late step of infection. Although the Env glycoprotein interacts with viral matrix proteins and cellular proteins associated with lipid rafts its possible role during the early replication events remains unclear. Truncation of the cytoplasmic tail CT of the Env glycoprotein is acquired by SIV in the course of adaptation to human cells and is known to be a determinant of SIV pathogenicity. Results We
