Functional role of cell-specific synaptic protein complexes in altered dopaminergic states.

The goal of the Baucum laboratory is to understand the functional organization of synaptic proteins in cell type-specific dendritic spines. Moreover, we want to determine how changes in dopamine signaling, either in animal models of Parkinson Disease (decreased dopamine) or following chronic treatment with drugs of abuse (increased dopamine) modulate synaptic organization in specific cell types. Specifically, we are evaluating the association of the dendritic-spine protein, spinophilin, with multiple other synaptic proteins. Spinophilin binds to F-actin and protein phosphatase 1 to modulate actin dynamics as well as the phosphorylation status of multiple synaptic targets. We are interested in identifying novel spinophilin associated proteins, identifying cell-specific differences in the spinophilin interactome, and determining cell-specific functional roles of spinophilin. Together, these data will enhance our understanding of cell-specific synaptic connectivity and identify putative therapeutic pathways that may be relevant in treating PD and drug addiction.
