Summary: Enables several functions, including dopamine:sodium symporter activity; identical protein binding activity; and organic cation transmembrane transporter activity. Involved in several processes, including metanephric proximal tubule development; monoamine transport; and monoatomic ion transmembrane transport. Located in apical plasma membrane and basolateral plasma membrane. Used to study acute kidney failure. Biomarker of asthma; extrahepatic cholestasis; and intrahepatic cholestasis. Orthologous to human SLC22A1 (solute carrier family 22 member 1). [provided by Alliance of Genome Resources, Jul 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.
