What is the function of M2 protein in influenza?

The M2 protein, which forms a homotetramer, has H+ ion channel activity that is sensitive to an anti-influenza virus drug, amantadine, and is activated by low pH. When the virus enters cells, the M2 ion channel is activated in endosomes to acidify inside the virion, facilitating viral uncoating.
