MSH: A 170-kDa transmembrane glycoprotein from the superfamily of ATP-BINDING CASSETTE TRANSPORTERS. It serves as an ATP-dependent efflux pump for a variety of chemicals, including many ANTINEOPLASTIC AGENTS. Overexpression of this glycoprotein is associated with multidrug resistance (see DRUG RESISTANCE, MULTIPLE).,CSP: gene product of the multidrug resistance gene mdr-1, believed to be a membrane spanning transporter that can pump a wide variety of cytotoxic agents out of the cell.,NCI: A protein that pumps substances out of cells. Cancer cells that have too much p-glycoprotein may not be killed by anticancer drugs.,NCI: Human p-glycoprotein-1 (1280 aa, 141 kDa) is encoded by the human ATP-binding cassette, sub-family B (MDR/TAP), member 1 (ABCB1) gene. The protein is an ATP-dependent, transmembrane transport/efflux pump glycoprotein that is expressed in liver, kidney, small intestine and brain.
