Multidrug Resistance Proteins

[同义词] Multidrug Resistance Proteins
[主题词] P-Glycoproteins
[中文释义] 多药抵抗蛋白质类
[英文释义] A subfamily of transmembrane proteins from the superfamily of ATP-BINDING CASSETTE TRANSPORTERS that are closely related in sequence to P-GLYCOPROTEIN. When overexpressed,they function as ATP-dependent efflux pumps able to extrude lipophilic drugs,especially ANTINEOPLASTIC AGENTS,from cells causing multidrug resistance (DRUG RESISTANCE,MULTIPLE). Although P-Glycoproteins share functional similarities to MULTIDRUG RESISTANCE-ASSOCIATED PROTEINS they are two distinct subclasses of ATP-BINDING CASSETTE TRANSPORTERS,and have little sequence homology.
