The role of ATP-binding cassette transporter A2 in childhood acute lymphoblastic leukemia multidrug resistance
Acute lymphoblastic leukemia (ALL) is one of the most prevalent hematologic malignancies in children. Although the cure rate of ALL has improved over the past decades, the most important reason for ALL treatment failure is multidrug resistance (MDR) phenomenon. The current study aims to explain the mechanisms involved in multidrug resistance of childhood ALL, and introduces ATP-binding cassette...
متن کاملA three-dimensional model for the substrate binding domain of the multidrug ATP binding cassette transporter LmrA.
Multidrug resistance presents a major obstacle to the treatment of infectious diseases and cancer. LmrA, a bacterial ATP-dependent multidrug transporter, mediates efflux of hydrophobic cationic substrates, including antibiotics. The substrate-binding domain of LmrA was identified by using photo-affinity ligands, proteolytic degradation of LmrA, and identification of ligand-modified peptide frag...
متن کاملMolecular basis of multidrug transport by ATP-binding cassette transporters: a proposed two-cylinder engine model.
ATP-binding cassette multidrug transporters are probably present in all living cells, and are able to export a variety of structurally unrelated compounds at the expense of ATP hydrolysis. The elevated expression of these proteins in multidrug resistant cells interferes with the drug-based control of cancers and infectious pathogenic microorganisms. Multidrug transporters interact directly with...
متن کاملTransmembrane transport of endo- and xenobiotics by mammalian ATP-binding cassette multidrug resistance proteins.
Multidrug Resistance Proteins (MRPs), together with the cystic fibrosis conductance regulator (CFTR/ABCC7) and the sulfonylurea receptors (SUR1/ABCC8 and SUR2/ABCC9) comprise the 13 members of the human "C" branch of the ATP binding cassette (ABC) superfamily. All C branch proteins share conserved structural features in their nucleotide binding domains (NBDs) that distinguish them from other AB...
