ABCB1 (ATP-binding cassette, subfamily B 1 gene) is also known as multidrug resistance 1 (MDR1) gene. MDR1 codes for P-glycoprotein 170 (P-gp), that is expressed at high levels in various cells and epithelial surfaces, including the epithelium of GI (gastrointestinal) tract. ABCB1 gene is located on human chromosome 7q.

Biochem/physiol Actions
ABCB1 (ATP-binding cassette, subfamily B 1 gene) or P-glycoprotein 170 (P-gp) participates in the development of tumors, especially in the carcinogenesis of colorectal. The encoded P-gp guards the body from environmental toxins and xenobiotics. The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance. The protein encoded by this gene is an ATP-dependent drug efflux pump for xenobiotic compounds with broad substrate specificity. It is responsible for decreased drug accumulation in multidrug-resistant cells and often mediates the development of resistance to anticancer drugs. This protein also functions as a transporter in the blood-brain barrier. [provided by RefSeq]
