CC -!- FUNCTION: Electrogenic sodium/bicarbonate cotransporter with a
CC Na(+):HCO3(-) stoichiometry varying from 1:2 to 1:3. May regulate
CC bicarbonate influx/efflux at the basolateral membrane of cells and
CC regulate intracellular pH. {ECO:0000256|ARBA:ARBA00037277}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 hydrogencarbonate(out) + Na(+)(out) = 2
CC hydrogencarbonate(in) + Na(+)(in); Xref=Rhea:RHEA:72215,
CC ChEBI:CHEBI:17544, ChEBI:CHEBI:29101;
CC Evidence={ECO:0000256|ARBA:ARBA00036309};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3 hydrogencarbonate(out) + Na(+)(out) = 3
CC hydrogencarbonate(in) + Na(+)(in); Xref=Rhea:RHEA:72219,
CC ChEBI:CHEBI:17544, ChEBI:CHEBI:29101;
CC Evidence={ECO:0000256|ARBA:ARBA00035820};
CC -!- SUBCELLULAR LOCATION: Basolateral cell membrane
CC {ECO:0000256|ARBA:ARBA00004554}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004554}. Cell membrane
