abstract：:In human immunodeficiency virus type 1 (HIV-1) and simian immunodeficiency virus (SIV) the gag gene encodes the precursor polyprotein Pr55Gag, which is cleaved by the viral protease to produce the major structural proteins. Recently, it has been shown that HIV and SIV gag RNAs contain internal ribosome entry sites (IR...
