Identification of chemical probes for ionotropic glutamate receptors
... Ligand-gated ion channels are cell surface proteins that play an important role in fast synaptic transmission and in the modulation of cellular activity. Glutamate receptor ion channels, in particular, mediate excitatory responses at the majority of CNS synapses and transduce the binding of a glutam ...
