Summary
Enables neutral amino acid transmembrane transporter activity. Acts upstream of or within amino acid transmembrane transport. Located in apical plasma membrane and brush border membrane. Is expressed in several structures, including metanephros. Orthologous to human SLC6A18 (solute carrier family 6 member 18). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
