== Function ==

[https://www.uniprot.org/uniprot/S4A7_HUMAN S4A7_HUMAN] Electroneutral sodium- and bicarbonate-dependent cotransporter with a Na(+):HCO3(-) 1:1 stoichiometry (PubMed:10347222, PubMed:12403779, PubMed:14578046, PubMed:14736710). Mediates the sodium-dependent bicarbonate transport important for pH recovery after acid load as well as for regulation of steady-state pH in the duodenum and vascular smooth muscle cells (By similarity). Plays a key role in macrophage acidification, mediating bicarbonate import into the cytoplasm which is crucial for net acid extrusion and maintenance of cytoplasmic pH during phagocytosis (PubMed:29779931). Provides cellular bicarbonate for de novo purine and pyrimidine synthesis and is a key mediator of de novo nucleotide synthesis downstream of mTORC1 signaling in proliferating cells (PubMed:35772404).[UniProtKB:Q8BTY2]<ref>PMID:10347222</ref> <ref>PMID:12403779</ref> <ref>PMID:14578046</ref> <ref>PMID:14736710</ref> <ref>PMID:29779931</ref> <ref>PMID:35772404</ref> Plays a key role in macrophage acidification, mediating bicarbonate import into the cytoplasm which is crucial for net acid extrusion and maintenance of cytoplasmic pH during phagocytosis.<ref>PMID:29779931</ref>
