Summary: Predicted to enable ATPase-coupled transmembrane transporter activity; phosphatidylcholine floppase activity; and xenobiotic transmembrane transporter activity. Involved in several processes, including Sertoli cell barrier remodeling; cellular response to external biotic stimulus; and establishment of endothelial blood-brain barrier. Located in Golgi membrane and external side of apical plasma membrane. Used to study colorectal adenocarcinoma; end stage renal disease; epilepsy (multiple); high grade glioma; and human immunodeficiency virus infectious disease. Biomarker of brain disease (multiple); cholestasis; human immunodeficiency virus infectious disease; metabolic dysfunction-associated steatotic liver disease; and obstructive sleep apnea. Human ortholog(s) of this gene implicated in several diseases, including carcinoma (multiple); drug dependence (multiple); human immunodeficiency virus infectious disease (multiple); inflammatory bowel disease (multiple); and leukemia (multiple). Orthologous to human ABCB1 (ATP binding cassette subfamily B member 1). [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.
