Structure and dynamics of influenza M2 proton channels from solid-state NMR

The A and B strains of influenza virus places a substantial burden on health, causing around 30 million illnesses, several hundred thousand hospitalizations, and a few tens of thousands of deaths every year in the United States alone. Developing novel antiviral and vaccines against influenza requires understanding the proteins employed by these infectious virions. The matrix-2 protein (M2) is an essential viral protein that conducts protons in the endosomes of infected host cells and induces membrane curvature to facilitate virus budding. M2's proton channel activity is encapsulated by a transmembrane domain (TM) that is targeted by the FDA-approved antiviral drugs amantadine and rimantadine to inhibit viral replication. Proton conduction by M2's TM is mediated by a His-xxx-Trp motif conserved in the otherwise disparate M2 from influenza A (AM2) and influenza B (BM2) strains.
