CC -!- FUNCTION: Does not show neutral amino acid transporter activity.
CC {ECO:0000269|PubMed:26240152}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000255}.
CC -!- TISSUE SPECIFICITY: Abundantly expressed in kidney, but not in
CC intestine. {ECO:0000269|PubMed:15286787}.
CC -!- POLYMORPHISM: Genetic variation in SLC6A18 is not a significant
CC predictor for elevated systolic or diastolic blood pressure and is not
CC associated with hypertension in the Japanese population
CC (PubMed:16340170). {ECO:0000269|PubMed:16340170}.
CC -!- DISEASE: Note=Genetic variations in SLC6A18 might contribute to the
CC disease phentotype in some individuals with iminoglycinuria or
CC hyperglycinuria, that carry variants in SLC36A2, SLC6A19 or SLC6A20
CC (PubMed:19033659). {ECO:0000269|PubMed:19033659}.
CC -!- SIMILARITY: Belongs to the sodium:neurotransmitter symporter (SNF) (TC
CC 2.A.22) family. SLC6A18 subfamily. {ECO:0000305}.
CC -!- CAUTION: The mouse ortholog protein is an active neutral amino acid
CC transporter. {ECO:0000269|PubMed:26240152}.
