Technical Data
Anion Exchanger 3 (AE3, Anion exchange protein 3, BAE3, brain band 3-like protein, Neuronal band 3-like protein, SLC4A3, Solute carrier family 4 member 3)
Anion exchangers (AE) are membranes proteins involved in the regulation of intracellular pH, cell volume regulation as well as in transepithelial acid/base transport. AE proteins are sodium-independent exchangers that mediates one-for-one exchange of extracellular Cl- for intracellular HCO3- ions resulting in intracellular acidification. AE proteins are encoded by a family of at least three related genes (AE1, AE2, and AE3). Numerous alternatively spliced isoforms of each AE gene are expressed in various tissues. AE proteins are exemplified by a large N-terminal cytoplasmic domain (~40-75kD) that provides binding sites for cytoskeleton protein, glycolytic enzymes and hemoglobin. The N-terminal cytoplasmic domains of AE2 are AE3 are more closely related than AE1. In fact, AE1 N-terminus is 300 aa shorter than both the AE2 and AE3. The C-terminal TM domain (~55kD) is highly conserved (~70% identity) among various AE, spans the lipid bilayer 12-14 times, and is able to mediate anion exchange by itself.
Human AE3 gene (chromosome 2q36) encodes a protein of 1233 aa (mouse/rat 1227 aa). AE3 is primarily expressed in excitable tissue such cardiac muscle, retina, and brain.
