Research in the Baucum laboratory focuses on the identification and characterization of synaptic protein complexes in a brain region called the striatum. The striatum is critical in allowing for fine motor control as well as being responsible for multiple effects of drugs of abuse. A decrease in dopamine innervation to the striatum underlies motor deficits associated with normal aging and age-related pathological conditions such as Parkinson Disease. Moreover, enhanced dopaminergic tone via blockade of dopamine reuptake or enhanced dopamine release caused by drugs of abuse such as cocaine and amphetamine can lead to motor and euphoric effects. How modulation of dopaminergic tone effects synaptic signaling and synaptic protein complexes in striatal medium spiny neurons has not been fully characterized.

The lab focuses on a synaptic protein, spinophilin, which is known to act as a scaffold, bringing multiple proteins together to allow for efficient organization and signaling. In particular, spinophilin binds to F-actin and can regulate actin and spine dynamics. Also, it binds to protein phosphatase 1 to target this phosphatase to various substrates, allowing for modulation of normal signaling. In collaboration with the proteomics core facility at IUPUI, we will be using mass spectrometry-based technologies to identify and quantify changes in specific spinophilin post-translational modifications and protein-protein interactions in animal models of Parkinson Disease and following exposure to drugs of abuse. These studies will be followed up with biochemical and imaging-based technologies to further characterize and understand the role that altered spinophilin signaling and protein complexes have on regulating changes observed under pathological conditions.
