SUBCELLULAR LOCALIZATION

plasma membrane

basic FUNCTION	Na+ (and Cl-) dependent plasma membrane transporter
	functional SLC6A6 plays a critical role in protecting against cisplatin-induced nephrotoxicity, possibly by attenuating a TP53-dependent pathway
	has the ability to use GABA as a substrate and Slc6a6/TauT-mediated GABA transport appears to be present at the inner blood-retinal barrier
	Na(+)- and Cl(-)-dependent, high-affinity, low-capacity transporter of taurine and beta-alanine
	may be important for taurine supply to the intestinal epithelium and for taurine capture between meals
	plays a critical role in renal function
	possible involvement in taurine uptake by Müller cells in retina
	critical for rescuing T cells from activation-induced cell death
	osmolyte transporter that is crucial for T-cell survival and T-cell mediated immune reactions

Type Gene Modification Chromosome rearrangement Protein expression Protein Function constitutional     --over   in spinal motor neurons of patients with ALS, and elevated expression of SLC6A6 directly contributes to increased taurine uptake in ALS motor neurons constitutional     --over   in mononuclear peripheral blood cells of type 2 diabetic patients, while presence of retinopathy is specifically associated with a drop in SLC6A6 overexpression, suggesting its possible involvement in this microangiopathic lesion

Candidate gene
Marker	is a novel pathological marker for stressed motor neurons in ALS
Therapy target
	System Type Disorder Pubmed neurology neurodegenerative   modulation of SLC6A6 and taurine may slow neuronal degeneration in ALS

ANIMAL & CELL MODELS

hereditary taurine deficiency in taurine-transporter knock-out (TAUT KO) mice results in disinhibition of striatal network activity, which can be corrected by taurine supplementation
