The function of Ensembl gene identifier ENSG00000109667 (SLC2A9, solute carrier family 2 member 9) is as follows. High-capacity urate transporter, which may play a role in the urate reabsorption by proximal tubules (PubMed:18327257, PubMed:18701466, PubMed:22647630, PubMed:28083649, PubMed:36749388). May have a residual high-affinity, low-capacity glucose and fructose transporter activity (PubMed:18327257, PubMed:18701466, PubMed:18842065). Transports urate at rates 45- to 60-fold faster than glucose (PubMed:18842065). Does not transport galactose (PubMed:28083649). May mediate small uptake of adenine but not of other nucleobases (PubMed:22647630). {ECO:0000269|PubMed:18327257, ECO:0000269|PubMed:18701466, ECO:0000269|PubMed:18842065, ECO:0000269|PubMed:22647630, ECO:0000269|PubMed:28083649}.
