Summary: Enables several functions, including cytoskeletal protein binding activity; efflux transmembrane transporter activity; and xenobiotic transmembrane transporter activity. Involved in several processes, including cellular response to dexamethasone stimulus; cellular response to estradiol stimulus; and embryonic process involved in female pregnancy. Located in external side of apical plasma membrane. Biomarker of diabetes mellitus; secondary hyperparathyroidism; status epilepticus; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in gout; hematologic cancer (multiple); renal cell carcinoma; and toxic encephalopathy. Orthologous to human ABCG2 (ATP binding cassette subfamily G member 2 (JR blood group)). [provided by Alliance of Genome Resources, Dec 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.
