Abstract: Nef is a 27 - 34 kD myristoylated protein unique to primate lentiviruses. A functional Nef gene is important for development of high viremia and simian AIDS in SIV infected rhesus macaques (1). In a transgenic mouse model expression of Nef protein alone when expressed under a CD4-promoter is sufficient to cause an AIDS like disease (2). A critical role for Nef in development of AIDS in humans is suggested by the observation that some individuals with a long-term nonprogressive HIV-1 infection are infected with viruses carrying naturally occurring Nef deletions (3-5). The mechanism of Nef action remains incompletely understood, but multiple lines of evidence point out to a role in modulation of cellular signaling pathways via physical and functional interactions with host cell proteins.
