Gene: Abcb1b (ATP-binding cassette, subfamily B (MDR/TAP), member 1B) Rattus norvegicus
Symbol: Abcb1b
Name: ATP-binding cassette, subfamily B (MDR/TAP), member 1B
Description: Predicted to have ATPase-coupled intramembrane lipid transporter activity and ATPase-coupled transmembrane transporter activity. Involved in several processes, including Sertoli cell barrier remodeling; animal organ development; and cellular response to external biotic stimulus. Localizes to Golgi membrane and external side of apical plasma membrane. Used to study brain disease (multiple); colorectal adenocarcinoma; end stage renal disease; and human immunodeficiency virus infectious disease. Biomarker of brain disease (multiple); cholestasis; human immunodeficiency virus infectious disease; non-alcoholic fatty liver disease; and obstructive sleep apnea. Human ortholog(s) of this gene implicated in several diseases, including Behcet's disease; allergic rhinitis; carcinoma (multiple); inflammatory bowel disease (multiple); and leukemia (multiple). Orthologous to human ABCB1 (ATP binding cassette subfamily B member 1); PARTICIPATES IN bile acid transport pathway; INTERACTS WITH (+)-pilocarpine; (+)-schisandrin B; 1,2-dimethylhydrazine.
Type: protein-coding
