Anion exchange protein 2 (AE2) is a membrane transport protein that in humans is encoded by the SLC4A2 gene.[5][6] AE2 is functionally similar to the Band 3 Cl/HCO3 exchange protein.

Mice have been used to explore the function of AE2. AE2 contributes to basolateral membrane HCO3 transport in the gastrointestinal tract.[7] AE2 is required for spermiogenesis in mice.[8] AE2 is required for normal osteoclast function.[9][10] The activity of AE2 is sensitive to pH.[11]

AE3 has been suggested as a target for prevention of diabetic vasculopathy.[12]
