- The influenza A M2 protein (AM2) is crucial for the virus's infection cycle, and understanding its structure could lead to new antiviral options.
- A study compared AM2 in two model membranes, nanodiscs and liposomes, using electron paramagnetic spectroscopy, revealing similar conformations in both systems despite differences in membrane fluidity.
- The research highlighted that cholesterol-induced conformational changes in AM2 were observable in both membranes, suggesting consistent functional behavior across different membrane models.
