NettetIN protein and assembled intasomes to aggre-gate. Fusion of the DNA binding protein Sso7d to theN terminus of IN results in a protein that is hyperactive in vitro, has markedly improved solu-bility properties, and retains activity in vivo when incorporated into HIV-1 virions ( 15). We therefore used Sso7d-IN to assemble HIV-1 intasomes for Nettet2. mar. 2024 · Integration of retroviral DNA into the host genome involves formation of integrase (IN)-DNA complexes termed intasomes. Here, we report the single-particle cryo-EM structure of the Rous sarcoma virus (RSV) strand transfer complex (STC) intasome produced with IN and a preassembled viral/target DNA substrate.
