Using Mass Spectrometry to Study Proteins and Cell Signaling

Study Proteins and Cell SignalingThe main focus of our lab is the development and use of mass spectrometric methods for the study of proteins and their roles in cellular signaling events. While great strides in understanding intracellular signal transduction have been made in recent years by using molecular biological techniques, we feel that a more complete understanding of the dynamics of intracellular decision-making processes can be gained only by studying the proteins directly. We use mass spectrometry as the main tool for our studies because of the wide variety of information about protein structure it can provide while requiring only small amounts of protein for analysis. We feel that the most efficient use of our technology is achieved by collaborating with outstanding molecular neuroscientists through the Protein Mass Spectrometry Core for Neuroscience.

Much of our work involves using stable isotope labeling by amino acids in cell culture (SILAC) and methods developed in our lab to study nerve growth factor signaling in primary neurons. One approach is to identify proteins become phosphorylated or bind to phosphorylated proteins in response to neurotrophins or other signaling molecules. We have also developed and regularly employ methods to study posttranslational modifications of proteins, and their roles in cell signaling. More recently we have combined click chemistry (BONCAT) and SILAC to study new protein synthesis in cells and brain slices.
