Title: P-Glycoprotein
Additional Names: Glycoprotein-P; P-gp; P-170; permeability glycoprotein
Literature References: Highly conserved cell-surface glycoprotein of Mr 170,000 daltons; protein product of the mammalian multidrug resistance (mdr) gene. Present in selective human tissues where it functions as an energy-dependent efflux pump. Increased expression in mammalian tumor cells is associated with multidrug resistance (MDR) to cancer chemotherapy agents.
