Summary
Enables basic amino acid transmembrane transporter activity. Acts upstream of or within regulation of arginine metabolic process. Predicted to be located in basolateral plasma membrane. Is expressed in heart; intestine; metanephros; and testis. Used to study lysinuric protein intolerance. Human ortholog(s) of this gene implicated in lysinuric protein intolerance. Orthologous to human SLC7A7 (solute carrier family 7 member 7). [provided by Alliance of Genome Resources, Jun 2025]

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.
