High-capacity urate transporter, which may play a role in the urate reabsorption by proximal tubules. May have a residual high-affinity, low-capacity glucose and fructose transporter activity. Transports urate at rates 45- to 60-fold faster than glucose. Does not transport galactose. May mediate small uptake of adenine but not of other nucleobases.
