The function of Ensembl gene identifier ENSG00000141485 (SLC13A5, solute carrier family 13 member 5) is as follows. High-affinity sodium/citrate cotransporter that mediates the entry of citrate into cells, which is a critical participant of biochemical pathways (PubMed:12445824, PubMed:12826022, PubMed:26324167, PubMed:26384929, PubMed:30054523, PubMed:33597751, PubMed:39622972). May function in various metabolic processes in which citrate has a critical role such as energy production (Krebs cycle), fatty acid synthesis, cholesterol synthesis, glycolysis, and gluconeogenesis (PubMed:12826022). Transports citrate into the cell in a Na(+)-dependent manner, recognizing the trivalent form of citrate (physiological pH) rather than the divalent form (PubMed:12445824, PubMed:12826022, PubMed:26324167, PubMed:26384929, PubMed:30054523, PubMed:33597751, PubMed:39622972). Can recognize succinate as a substrate, but its affinity for succinate is several fold lower than for citrate (PubMed:26324167). The stoichiometry is probably 4 Na(+) for each carboxylate, irrespective of whether the translocated substrate is divalent or trivalent, rendering the process electrogenic (PubMed:12445824, PubMed:12826022, PubMed:39622972). Involved in the regulation of citrate levels in the brain (By similarity). {ECO:0000250|UniProtKB:Q67BT3, ECO:0000269|PubMed:12445824, ECO:0000269|PubMed:12826022, ECO:0000269|PubMed:26324167, ECO:0000269|PubMed:26384929, ECO:0000269|PubMed:30054523, ECO:0000269|PubMed:33597751, ECO:0000269|PubMed:39622972}.
