New look at multitalented protein sheds light on mysteries of HIV
Date:10/14/2010

the different stages of the virus's development, and look at what Gag's conformation was at these various stages," Nanda says. "We saw conformations that had never been seen before."

Nanda describes the team's first paper* on the subject as an important first step in describing their observational method, which was a joint effort between NIST, the National Cancer Institute and Carnegie-Mellon University. They plan another paper detailing what the method has revealed about HIV.

"Our efforts have not yet shown us how many steps are involved in Gag's work assembling an HIV particle, but at least we can see what it looks like in each major interaction that likely occurs in the cell during assembly," Nanda says. "It may allow us to characterize them for the first time."

Nanda says that their technique will also allow scientists to examine large classes of membrane proteins, which like Gag are notoriously hard to examine.
