Involved in actively transporting phosphate into cells via Na(+) cotransport in the renal brush border membrane (PubMed:12324554, PubMed:20335586, PubMed:26047794, PubMed:8327470). The cotransport has a Na(+):Pi stoichiometry of 3:1 and is electrogenic (By similarity). {ECO:0000250|UniProtKB:Q06496, ECO:0000269|PubMed:12324554, ECO:0000269|PubMed:20335586, ECO:0000269|PubMed:26047794, ECO:0000269|PubMed:8327470}. This is the function of Ensembl gene identifier ENSG00000131183 (SLC34A1, solute carrier family 34 member 1).
