In vitro evolution and analysis of HIV-1 LTR-specific recombinases

Current antiretroviral therapies would greatly benefit from the concurrent removal of integrated HIV-1 proviral DNA from the patient's cells. In this review, we describe an experimental strategy that allowed the engineering and functional analysis of a HIV-1 LTR-specific recombinase (Tre-recombinase). We furthermore provide protocols that are utilized for the investigation of Ire's antiretroviral activity in infected tissue cultures as well as in infected humanized Rag2(-/-)gamma c(-/-) mice.
