The function of SLC16A7 (solute carrier family 16 member 7, Ensembl gene identifier ENSG00000118596) is as follows. Proton-coupled monocarboxylate symporter. Catalyzes the rapid transport across the plasma membrane of monocarboxylates such as L- lactate, pyruvate and ketone bodies, acetoacetate, beta-hydroxybutyrate and acetate (PubMed:32415067, PubMed:9786900). Dimerization is functionally required and both subunits work cooperatively in transporting substrate (PubMed:32415067). {ECO:0000269|PubMed:32415067, ECO:0000269|PubMed:9786900}.
