Anion:Cation Symporter (ACS) Family
Tissue Specificity Expressed in the liver and kidney. It isdetected in proximal tubules in renal cortex as well as sometubules and glomeruli, with highest expression at the apical sideof proximal tubules (at protein level).
Function This voltage-driven, multispecific, organic anion transporter mediates the transport of para-aminohippurate (PAH), estrone sulfate, estradiol-17-beta-glucuronide, bumetanide, and ochratoxin A. Isoform 2 functions as urate efflux transporter on the apical side of renal proximal tubule and is likely to act as an exit path for organic anionic drugs as well as urate in vivo. May be involved in actively transporting phosphate into cells via Na(+) cotransport.
Endogenous Substrate(s) Na+
