Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables biotin transmembrane transporter activity; efflux transmembrane transporter activity; and riboflavin transmembrane transporter activity. Involved in biotin transport and riboflavin transport. Located in apical plasma membrane. Is expressed in several structures, including alimentary system; brain; early conceptus; genitourinary system; and hemolymphoid system. Used to study erythropoietic protoporphyria and hyperuricemia. 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)).
