일반 설명
Membrane Preparations for ATPase Assays are suitable for drug-efflux transporter interaction studies based on ATPase activity determination, and could be used for differentiation between transporter substrates and inhibitors.
애플리케이션
The ATPase assay is an in vitro membrane assay designed to indicate the nature of the interaction between the compound and the transporter. By measuring ATPase activity, both activation and inhibition of transporters can be investigated using membranes from baculovirus-infected insect cells or mammalian cell membranes containing high levels of human or rodent wild-type transporters. ABC transporters mediate the transport of substrates against a concentration gradient using energy derived from ATP hydrolysis, which is proportional to the transporter activity and could easily be detected with a colorimetric method.
To assess activation, ABC transporter-rich membranes are incubated with various (typically in 8) concentrations of the test article and the effect on basal ATPase activity is measured. Compounds that stimulate ATPase are generally considered substrates for the transporter. To assess inhibition, a test article′ ability to modify the activity of a given ABC transporter stimulated with its prototypical substrates is examined. The activation and inhibition tests are complementary assays.
Stimulation detected in the activation assay indicate that the compound is a transported substrate of the transporter, while interactions detected in the inhibition test indicate interaction of the test compounds with the transporter, but do not give information on the nature (substrate or inhibitor) of the interaction. In some cases inhibitors or slowly transported compounds may inhibit the baseline transporter ATPase activity as well.
Slowly transported substrates often do not stimulate the ATPase activity in a detectable extent; however the existing interaction can be identified in the inhibition assay.

Multidrug ABC transporters such as P-glycoprotein (P-gp/MDR1/ABCB1) and multidrug resistance protein 1 (MRP1/ABCC1) play an important role in the extrusion of drugs from the cell and their overexpression can be a cause of failure of anticancer and antimicrobial chemotherapy. Recently

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

The multidrug resistance-associated protein (MRP) mediates the cellular excretion of many drugs, glutathione S-conjugates (GS-X) of lipophilic xenobiotics and endogenous cysteinyl leukotrienes. Increased MRP levels in tumor cells can cause multidrug resistance (MDR) by decreasing the intracellular drug concentration. The

Adaptive immune responses begin after antigen-bearing dendritic cells (DCs) traffic from peripheral tissues to lymph nodes. Here, we show that DC migration from skin to lymph nodes utilizes the leukotriene C(4) (LTC(4)) transporter multidrug resistance-associated protein 1 (MRP1). DC mobilization
