Summary: Predicted to enable amino acid transmembrane transporter activity; peptide antigen binding activity; and protein heterodimerization activity. Predicted to be involved in L-cystine transport and amino acid transmembrane transport. Located in brush border membrane. Is expressed in several structures, including metanephros and midgut. Used to study cystinuria. Human ortholog(s) of this gene implicated in cystinuria. Orthologous to human SLC7A9 (solute carrier family 7 member 9). [provided by Alliance of Genome Resources, Nov 2024]

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.
