Summary: Predicted to enable several functions, including ATP binding activity; ATP hydrolysis activity; and ATPase-coupled intramembrane lipid transporter activity. Involved in several processes, including cellular hyperosmotic salinity response; cellular response to L-glutamate; and cellular response to borneol. Located in apical plasma membrane and brush border membrane. Biomarker of brain disease (multiple); end stage renal disease; human immunodeficiency virus infectious disease; liver disease (multiple); 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.
