is a unique motif involved in regulating the packaging of the viral genome into the capsid. It is composed of four stem-loop (SL) structures with a major splicing donor site embedded in the second SL.
*DIS, or dimer initiation site, is a highly conserved RNA-RNA interacting sequence constituting the SL1 stem-loop in the Psi packaging element of many retroviruses. DIS is characterized by a conserved stem and palindromic loop that forms a kissing-loop complex
