Background
The ABCG2 multidrug transporter is a membrane protein from the ATP-binding cassette (ABC) transporter family, specifically the G-subfamily. Also know as the breast cancer resistance protein (BCRP), ABCG2 has physiological roles in various tissue cells including the mammary gland and the blood-brain, blood-testis, and maternal-fetal barriers.[1] ABCG2 protects cells by exporting xenobiotic molecules out of the cell using ATP hydrolysis. ABCG2 also affects the pharmacokinetics of many drugs and contributes to multidrug resistance.[2]

Disease
Cancer
ABCG2 contributes to multidrug resistance in cancer cells by exporting anti-tumor drugs out of cells which introduces an obstacle in cancer treatment.[1]
