Imaging solves mystery of how large HIV protein functions to form infectious virus

Understanding how HIV replicates within cells is key for developing new therapies that could help nearly 40 million people living with HIV globally. Now, a team of scientists from the Salk Institute and Rutgers University have for the first time determined the molecular structure of HIV Pol, a protein that plays a key role in the late stages of HIV replication, or the process through which the virus propagates itself and spreads through the body. Importantly, determining the molecule's structure helps answer longstanding questions about how the protein breaks itself apart to advance the replication process. The discovery, published in Science Advances on July 6, 2022, reveals a new vulnerability in the virus that could be targeted with drugs.
