Protein:RNA interaction between NC and psi occurs through two specific zinc finger domains within NC. Inhibition studies suggest that zinc chelators that inhibit zinc binding to these fingers also inhibit retroviral replication (68,69). The p6 protein is the most C-terminal portion of HIV-1 Gag (a region that is variable among different retroviruses) and its role is less well understood. The Pol Polyprotein PR-RT-IN PR Gag and Gag–Pol polyproteins that are incorporated into the virion are immature and must be cleaved by PR to produce mature infectious viruses.

17 Although core elements use factors common to most cell types, regulatory-enhancer elements provide the virus with the capacity for complex and variable expression based on the activity of cell-type-specific regulatory factors. Regulatory-control elements consist of an array of DNA sequences (that is, enhancers) generally located more distal to the RNA start site than core elements. Enhancers are short DNA sequences, 10 to 25 base pairs in length, that function as target binding sites for transcriptional regulators.
