Drug transporter protein

Drug transporter proteins are specialized membrane-spanning proteins that facilitate the movement of ions, peptides, small molecules—including many pharmaceutical agents—lipids, and macromolecules across biological membranes. They play critical roles in pharmacokinetics by regulating the absorption, distribution, metabolism, and excretion of drugs. Major classes include ATP-binding cassette (ABC) transporters—which often mediate multidrug resistance in cancer by actively exporting chemotherapeutic agents out of cells—P-type ATPases that pump cations using energy from ATP hydrolysis, and solute carrier (SLC) families involved in secondary active transport or facilitated diffusion. The broad term "drug transporter protein" is not a precise molecular target but refers to a large group comprising many distinct proteins with diverse substrate specificities and physiological roles[1][3][4]. > Note: The entry "Drug transporter protein" is too generic for structured data extraction about a single molecular entity. It encompasses numerous distinct proteins with different names/functions/families; therefore it should be flagged as incorrect for use as a canonical target name. For structured information on therapeutic targeting or pharmacology research purposes, it is necessary to specify an exact member such as "P-glycoprotein" (ABCB1), "Organic anion transporting polypeptide 1B1" (SLCO1B1), etc.[6]
