Mediates sodium- and chloride-dependent transport of taurine (  ). Mediates transport of beta-alanine . Can also mediate transport of hypotaurine and gamma-aminobutyric acid (GABA) (By similarity).
Sodium-dependent taurine and beta-alanine transporter. Chloride ions are necessary for optimal uptake.
Subcellular locations: Cell membrane
Expressed abundantly in placenta and skeletal muscle, at intermediate levels in heart, brain, lung, kidney and pancreas and at low levels in liver.
