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 کاملAn ATP-binding cassette transporter-like complex governs cell-wall hydrolysis at the bacterial cytokinetic ring.
ATP-binding cassette transporters are ubiquitous membrane protein complexes that move substrates across membranes. They do so using ATP-induced conformational changes in their nucleotide-binding domains to alter the conformation of the transport cavity formed by their transmembrane domains. In Escherichia coli, an ATP-binding cassette transporter-like complex composed of FtsE (nucleotide-bindin...
متن کاملDisruption of lolCDE, encoding an ATP-binding cassette transporter, is lethal for Escherichia coli and prevents release of lipoproteins from the inner membrane.
ATP-binding cassette transporter LolCDE was previously identified, by using reconstituted proteoliposomes, as an apparatus catalyzing the release of outer membrane-specific lipoproteins from the inner membrane of Escherichia coli. Mutations resulting in defective LolD were previously shown to be lethal for E. coli. The amino acid sequences of LolC and LolE are similar to each other, but the nec...
متن کاملFunctional analysis of ATP-binding cassette transporter of Streptomyces coelicolor
Article history: Received on: 04/02/2014 Revised on: 28/02/2014 Accepted on: 12/03/2014 Available online: 28/07/2014 ATPbinding cassette (ABC) transporters are characterized as multi drug resistant transporters utilizing ATP hydrolysis. The SCO5113 (GeneID: 1100554) encoding a multidrug resistance ABC transporter in Streptomyces coelicolor was expressed in E.coli BL21 (DE3) plysS, using pET 21 ...
متن کاملATP-binding cassette transporter A1: regulation of cholesterol efflux.
The ATP-binding cassette transporter A1 (ABCA1) is involved in the regulation of cholesterol efflux from cells. Mutations in ABCA1 give rise to familial high-density lipoprotein (HDL) deficiency and Tangier disease, which is characterized by very low levels of HDL in plasma and cholesteryl ester accumulation in tonsils and other reticuloendothelial cells. The mechanism of action of ABCA1 is sti...
