Electronic Theses and Dissertations
The serotonin transporter (SERT) is a member of the neurotransmitter sodium symporter family of transporters. SERT controls the magnitude and duration of serotonergic neurotransmission by facilitating the reuptake of serotonin back into the pre-synaptic neuron and is thus a target for antidepressants. Selective serotonin re-uptake inhibitors (SSRIs) such as fluoxetine, are commonly prescribed to treat depression. SSRIs act by blocking reuptake and prolonging serotonin signaling. However, significant problems regarding selectivity and mechanisms of action of these drugs remain unresolved. The structures of SERT and related transporters have been determined and serve as useful structural models. However, they are typically mutated …

Electronic Theses and Dissertations
Recent advances in technology have led to the determination of numerous notable structures of membrane proteins. While they provide valuable information about the structure of membrane proteins these studies often provide static images with potentially limited dynamics, and structural determination often requires truncation of flexible regions, and often utilizes bacterial homologs given the need for stable, heterologous overexpression. In order to better understand allostery at a molecular level, state-dependent crosslinking studies coupled with multidimensional mass spectrometry (MS) were conducted on glycine receptor (GlyR) stabilized in different allosteric states. Predominant allosteric states were stabilized using wild type or mutated receptor in …
