Structural biology of HIV-1 [video]

A video walkthrough of a new review article on HIV structural biology. HIV-1 has been analysed by structural biology techniques more than any other virus, with partial or complete structures known for all 15 of its protein components and additional structures determined for substrate- and host factor-bound complexes. Three-dimensional molecular structures can provide detailed information on biological mechanisms and, for cases in which the molecular function affects human health, can significantly aid in the development of therapeutic interventions.

For almost 25 years, key components of the lentivirus HIV-1, including the envelope glycoproteins, the capsid and the replication enzymes reverse transcriptase, integrase and protease, have been scrutinized to near atomic-scale resolution. Moreover, structural analyses of the interactions between viral and host cell components have yielded key insights into the mechanisms of viral entry, chromosomal integration, transcription and egress from cells. This review article discusses recent advances in HIV-1 structural biology, focusing on the molecular mechanisms of viral replication and on the development of new therapeutics:
