Anion exchange protein 3 is a membrane transport protein that in humans is encoded by the SLC4A3 gene.^[5]^[6] AE3 is functionally similar to the Band 3 Cl⁻/ HCO3⁻ exchange protein but it is expressed primarily in brain neurons and in the heart. Like AE2 its activity is sensitive to pH.^[7]^[8] AE3 mutations have been linked to seizures.^[9]^[10]
