Synonyms HNBC1; KNBC; NBC1; NBCE1; NBCe1-A; Na(+)/HCO3(-) cotransporter; SLC4A4; Sodium bicarbonate cotransporter; Solute carrier family 4 member 4; hhNMC; kNBC1; pNBC
DT Family Anion Exchanger (AE) Family ;
Tissue Specificity Isoform 1 is expressed in pancreas and to alower extent in heart, skeletal muscle, liver, parotid salivaryglands, prostate, colon, stomach, thyroid, brain and spinal chord.Corneal endothelium cells express only isoform 1 (at proteinlevel). Isoform 2 is specifically expressed in kidney at the levelof proximal tubules.
Function This transporter may regulate bicarbonate influx/efflux at the basolateral membrane of cells and regulate intracellular pH. Electrogenic sodium/bicarbonate cotransporter with a Na(+):HCO3(-) stoichiometry varying from 1:2 to 1:3.
Endogenous Substrate(s) Na+
