Three-dimensional Structure of P-glycoprotein
15 Oct 2004
Abstract excerpt
Multidrug resistance of cancer cells and pathogens is a serious clinical problem. A major factor contributing to drug resistance in cancer is the over-expression of P-glycoprotein, a plasma membrane ATP-binding cassette (ABC) drug efflux pump. Three-dimensional structural data with a resolution limit of approximately 8 A have been obtained from two-dimensional crystals of P-glycoprotein trapped in the...
