WebbFIGURE 1 Life cycle of influenza virus showing the steps in which the M2 ion channel functions. The life cycle and role of the M2 protein are similar for both strains of influenza virus. The M2 proton channels function while the virion is contained in the endosome (step 3) to permit subsequent uncoating.For certain subtypes of influenza A virus the M2 … Sodium channels consist of large alpha subunits that associate with proteins, such as beta subunits. An alpha subunit forms the core of the channel and is functional on its own. When the alpha subunit protein is expressed by a cell, it is able to form channels that conduct Na in a voltage-gated way, even if beta subunits or other known modulating proteins are not expressed. When access…
