Summary: Predicted to enable ATPase-coupled transmembrane transporter activity and protein heterodimerization activity. Predicted to contribute to ATP binding activity; ATP hydrolysis activity; and cholesterol transfer activity. Involved in several processes, including cholesterol homeostasis; response to muscle activity; and triglyceride homeostasis. Predicted to be located in apical plasma membrane. Predicted to be part of ATP-binding activity cassette (ABC) transporter complex and receptor complex. Predicted to be active in plasma membrane. Biomarker of cholestasis and metabolic dysfunction-associated steatotic liver disease. Human ortholog(s) of this gene implicated in arteriosclerosis; familial hyperlipidemia; obesity; and sitosterolemia 1. Orthologous to human ABCG8 (ATP binding cassette subfamily G member 8).

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.
