Protein attributes

Sequence length	1280 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Energy-dependent efflux pump responsible for decreased drug accumulation in multidrug-resistant cells.
Catalytic activity	ATP + H2O + xenobiotic(In) = ADP + phosphate + xenobiotic(Out).
Subunit structure	Interacts with PSMB5. Ref.10
Subcellular location	Cell membrane; Multi-pass membrane protein By similarity.
Tissue specificity	Expressed in liver, kidney, small intestine and brain.
Polymorphism	Genetic variation in ABCB1 may play a role in patients who do not respond to drug treatment.
Involvement in disease	Inflammatory bowel disease 13 (IBD13) [MIM:612244]: A chronic, relapsing inflammation of the gastrointestinal tract with a complex etiology. It is subdivided into Crohn disease and ulcerative colitis phenotypes. Crohn disease may affect any part of the gastrointestinal tract from the mouth to the anus, but most frequently it involves the terminal ileum and colon. Bowel inflammation is transmural and discontinuous; it may contain granulomas or be associated with intestinal or perianal fistulas. In contrast, in ulcerative colitis, the inflammation is continuous and limited to rectal and colonic mucosal layers; fistulas and granulomas are not observed. Both diseases include extraintestinal inflammation of the skin, eyes, or joints. Note: Disease susceptibility is associated with variations affecting the gene represented in this entry. Ref.21
Sequence similarities	Belongs to the ABC transporter superfamily. ABCB family. Multidrug resistance exporter (TC 3.A.1.201) subfamily. [View classification] Contains 2 ABC transmembrane type-1 domains. Contains 2 ABC transporter domains.
Sequence caution	The sequence AAM49149.1 differs from that shown. Reason: Erroneous gene model prediction.
