Name Sodium bicarbonate cotransporter 3
Synonyms
  1. Bicarbonate transporter
  2. Sodium bicarbonate cotransporter 2
  3. Sodium bicarbonate cotransporter 2b
  4. Solute carrier family 4 member 7
Gene Name SLC4A7
Protein Type Transporter
Biological Properties
General Function Involved in anion transport
Specific Function Electroneutral sodium- and bicarbonate-dependent cotransporter with a Na(+):HCO3(-) 1:1 stoichiometry. Regulates intracellular pH and may play a role in bicarbonate salvage in secretory epithelia. May also have an associated sodium channel activity.
