The Matrix-2 (M2) protein is a proton-selective viroporin, integral in the viral envelope of the influenza A virus. The channel itself is a homotetramer (consists of four identical M2 units), where the units are helices stabilized by two disulfide bonds, and is activated by low pH. The M2 protein is encoded on the seventh RNA segment together with the M1 protein. Proton conductance by the M2 protein in influenza A is essential for viral replication. Influenza B and C viruses encode proteins with similar function dubbed "BM2" and "CM2" respectively. They share little similarity with M2 at the sequence level, despite a similar overall structure and mechanism. (Wikipedia).
Sodium Potassium Pump - Active Transport
This Biology video tutorial explains how the sodium potassium pump works inside the cell membrane. This protein based pump is an example of active transport which requires the use of ATP energy to power the movement of particles up against the concentration gradient - that is to move the
