The function of ENSG00000157103 (SLC6A1, solute carrier family 6 member 1) is as follows. Mediates transport of gamma-aminobutyric acid (GABA) together with sodium and chloride and is responsible for the reuptake of GABA from the synapse (PubMed:30132828). The translocation of GABA, however, may also occur in the reverse direction leading to the release of GABA (By similarity). The direction and magnitude of GABA transport is a consequence of the prevailing thermodynamic conditions, determined by membrane potential and the intracellular and extracellular concentrations of Na(+), Cl(-) and GABA (By similarity). Can also mediate sodium- and chloride-dependent transport of hypotaurine but to a much lower extent as compared to GABA (By similarity). {ECO:0000250|UniProtKB:P23978, ECO:0000250|UniProtKB:P31648, ECO:0000269|PubMed:30132828}.
