The [[Influenza]] A Virus viral envelope is dotted with various [[ion channels]] including [[M2 Proton Channel|M2 Proton Channels]]. The <scene name='Amantadine/M2/1'>M2 protein</scene> plays a critical role in the life cycle of the Influenza virus. It enables hydrogen ions to enter the virion form the endosome. The result of this is a more acidic environment within the virus, causing dissociation of the viral matrix protein M1 from the ribonucleoprotein RNP. Dissociation of the viral matrix protein is a crucial step in uncoating of the virus and exposing its contents to the cytoplasm of the host cell, allowing the virus to hijack the cellular machinery to replicate. <scene name='Amantadine/Bound/1'>Amantadine binds to the pore</scene> formed by the M2 protein, utilizing Val 27, Ala 30 and Ser 31 in each M2 protein chain, effectively disabling the protein from transferring protons into the viral particle.<ref>PMID: 18235503</ref> | The [[Influenza]] A Virus viral envelope is dotted with various [[ion channels]] including [[M2 Proton Channel|M2 Proton Channels]].
