Computational Studies of Glutamate Transporters
Glutamate is the major excitatory neurotransmitter in the human brain whose binding to receptors on neurons excites them while excess glutamate are removed from synapses via transporter proteins. Determination of the crystal structures of bacterial aspartate transporters has paved the way for computational investigation of their function and dynamics at the molecular level. Here, we review mole...
متن کاملGlutamate transporters in bone.
In the central nervous system Na(+)-dependent glutamate transporters bind extracellular glutamate and transport it into cells surrounding the synapse, terminating excitatory signals. These glutamate transporters also function as ion channels. The glutamate transporter, GLAST-1, is expressed in the plasma membrane of osteoblasts and osteocytes and is the same molecular weight as in brain. Thus i...
متن کاملSmall-scale molecular motions accomplish glutamate uptake in human glutamate transporters.
Glutamate transporters remove glutamate from the synaptic cleft to maintain efficient synaptic communication between neurons and to prevent glutamate concentrations from reaching neurotoxic levels. Glutamate transporters play an important role in ischemic neuronal death during stroke and have been implicated in epilepsy and amytropic lateral sclerosis. However, the molecular structure and the g...

developed that BNP1 might have alternative, or at least additional roles. First, mutations in a BNP1 homolog in C. elegans (eat-4) were noted to cause presynaptic An essential step in chemical synaptic transmission in-deficits in glutamatergic transmission (Berger et al., volves concentration of neurotransmitter into synaptic 1998). Second, immunocytochemical studies of BNP1 vesicles, allowing ...
متن کاملGlutamate transporters: The arrestin connection
The neurotransmitter glutamate is a major player in the physiology and pathology of the nervous system. Glutamate receptors are responsible for fast excitatory neurotransmission underlying the sensory, motor and cognitive functions of the nervous system. However, overstimulation of these receptors, and in particular those of the NMDA receptor subtype, is associated with neuronal death in acute ...
