Structural and functional elements involved in encapsidation and dimerization of HIV-1and HIV-2 genomic RNAs. (A) The landmark sequences with known functions are indicated by boxes (see Fig. 1A). (B, C) The encapsidation, dimerization, and regulatory elements in HIV-2 (Griffin et al. 2001; Dirac et al. 2002; Lanchy et al. 2003) and HIV-1(McBride and Panganiban 1996; Abbink and Berkhout 2002; Berkhout et al. 2002; Clever et al. 2002; Russell et al. 2002) are indicated by open, closed, and hatched boxes, respectively. The described short- or long-range interactions between structural elements are indicated with brackets. The asterisk indicates palindrome (GAGUGCUU/C) locations in HIV-1and HIV-2.
