Summary: Predicted to enable ABC-type xenobiotic transporter activity and efflux transmembrane transporter activity. Involved in renal tubular secretion and response to insecticide. Predicted to be located in plasma membrane. Predicted to be part of ATP-binding activity cassette (ABC) transporter complex. Predicted to be active in membrane. Is expressed in adult head. Human ortholog(s) of this gene implicated in several diseases, including cholestasis (multiple); drug dependence (multiple); human immunodeficiency virus infectious disease (multiple); inflammatory bowel disease (multiple); and liver disease (multiple). Orthologous to several human genes including ABCB1 (ATP binding cassette subfamily B member 1); ABCB4 (ATP binding cassette subfamily B member 4); and ABCB5 (ATP binding cassette subfamily B member 5).
