Substrate recognition by the retroviral IN enzyme is critical for retroviral integration. To catalyze this recombination event, IN must recognize and act on two types of substrates, viral DNA and host DNA, yet the necessary interactions exhibit markedly different degrees of specificity. Although particular sequences at the viral DNA termini are recognized by IN, many host DNA sequences can serve as the target for integration. Over the last decade, both in vitro and in vivo data have contributed to our understanding of how IN recognizes its substrates. This review provides an overview of the sequence and structure requirements for recognition of viral and host DNA by different retroviral INs and discusses recent progress in mapping protein domains involved in these interactions.
