Prior studies of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors, including that of GluA3 AMPA receptor subunit, have shown that alternative mRNA splicing, which generates flip and flop variants with different amino acid sequences, gives rise to functional differences between the two variants. The goal of this MS thesis is to investigate the basic gating properties of the heteromeric complex channels formed from GluA2R/GluA3 AMPA receptor subunits and the different variants between the two subunits. The hypothesis to be tested is whether different GluA3 variants affect the channel gating properties when each of the variants is in a complex with the Q/R-site edited …

The propagation of information in the central nervous system is, in essence, the flow of ions. Neurons connect with each other to form neural circuits that perform distinct functions, and these connections are formed through synapses. Excitatory and inhibitory synapses determine the excitability of a neuron, which further dictates the firing of action potentials. The major ion channels that mediate the transmission at the excitatory synapses are ionotropic glutamate receptors, among which AMPA receptors are responsible for the fast excitatory transmission. Therefore, the functionalities of AMPA receptors substantially affect the information flow, and dysfunction of them could potentially cause many …
