Neurotransmitter Transporters
Neurotransmitters are released into the extracellular space during synaptic transmission. The actions of these chemical signals are terminated through active uptake by transporters that are located in the plasma membrane of neurons and glial cells. Transporters harness electrochemical gradients to force the movement of transmitter back into cells against its concentration gradient. These protei...
متن کاملTransporters Revealed
The subfamily C ATP-binding cassette (ABCC) transporters mediate multidrug resistance and ion conductance regulation. Recent atomic or near-atomic resolution structures of three physiologically significant ABCC transporters (MRP1, SUR1, and CFTR), determined by using single-particle cryo-electron microscopy (cryo-EM), reveal structural details that help explain the wide functional diversity of ...
متن کاملGlucose transporters in obesity
L’obCsitC, pathologie frtquente dans les sociCtCs industrialiskes, est caractQiste par un sur-diveloppement du tissu adipeux. Nous avons CtudiC un moditle animal d’obksitk, le rat Zucker gCnCtiquement obkse. D b l’iige de 30 jours, les cellules adipeuses des rats mutants transportent beaucoup plus de glucose que celles des temoins normaux des memes portCes. Cette anomalie repose sur une augment...
متن کاملPorters and neurotransmitter transporters.
Uptake of neurotransmitters involves multiple transporters acting in different brain locations under different physiological conditions. The vesicular transporters are driven by a proton-motive force generated by a V-ATPase and their substrates are taken up via proton/substrate exchange. The plasma membrane transporters are driven by an electrochemical gradient of sodium generated by a Na+/K(+)...
متن کاملABC transporters: bacterial exporters.
The ABC transporters (also called traffic ATPases) make up a large superfamily of proteins which share a common function and a common ATP-binding domain. ABC transporters are classified into three major groups: bacterial importers (the periplasmic permeases), eukaryotic transporters, and bacterial exporters. We present a comprehensive review of the bacterial ABC exporter group, which currently ...
