An antiport is an integral membrane transport protein that simutaneously transports two different molecules, in opposite directions, across the membrane.The example below depicts the process by which HCl is secreted into the lumen on the stomach.n antiport is an integral membrane transport protein that simutaneously transports two different molecules, in opposite directions, across the membrane.
Cells also contain anion antiporters such as the Band 3 (or AE1) anion transport protein. This cotransporter is an important integral protein in mammalian erythrocytes and moves chloride ion and bicarbonate ion in a one-to-one ratio across the plasma membrane based only on the concentration gradient of the two ions.
