    Background
    The Influenza A Virus (IAV) M2 protein is a 97-amino acid, integral membrane viroporin essential for the viral life cycle, functioning as a homotetrameric, pH-activated, proton-selective ion channel. Its structure consists of an N-terminal ectodomain (residues 1–24) critical for virion incorporation, a transmembrane domain (residues 25–43) forming the channel core, and a C-terminal domain (residues 44–97) that includes an amphipathic helix and an unstructured tail involved in virus assembly and budding. Key residues, His37 and Trp41, serve as the proton sensor and channel gate, respectively. Upon endosomal acidification during viral entry, M2 mediates proton influx into the virion, facilitating release of viral ribonucleoproteins for replication. Subsequently, M2 maintains optimal pH in the trans-Golgi network to prevent premature hemagglutinin activation, while its C-terminal amphipathic helix induces membrane curvature required for viral budding and scission. M2 activity is regulated by pH and host protein interactions, and although it is a target of antivirals like amantadine, drug resistance is common due to mutations in the transmembrane domain.
