Landon King Lab
The Landon King Lab studies aquaporins water-specific membrane channel proteins. We hope to understand how these proteins contribute to water homeostasis in the respiratory tract and how their expression or function may be altered in disease states.

Mass Spectrometry Core
The Mass Spectrometry Core identifies and quantifies proteins that change expression in well-characterized protein fractions from cancerous cells or tissues. This includes identifying and quantifying changes in binding partners and post-translational modifications. Column chromatography and gel electrophoresis-based one and two-dimensional separations of protein complexes coupled to mass spectrometry are used. Techniques such as difference gel electrophoresis (DIGE), isobaric tag for relative and absolute quantitation (iTRAQ) and 18O-labeling as well as non-labeling methods (MudPit, multi-dimensional protein identification technology) are available for quantifying relative differences in protein expression and post-translational modifications. We developed methods to detect post-translational modifications such as LCMS methods to accurately determine the intact mass of proteins, selective fluorescent labeling of S-nitrosothiols (S-FLOS) to detect nitrosated cysteines in proteins, and i...on mapping methods to map post-translational modifications that produce a signature mass or mass difference when the modified peptide is fragmented. view more

Michael Caterina Lab
The Caterina lab is focused on dissecting mechanisms underlying acute and chronic pain sensation. We use a wide range of approaches, including mouse genetics, imaging, electrophysiology, behavior, cell culture, biochemistry and neuroanatomy to tease apart the molecular and cellular contributors to pathological pain sensation. A few of the current projects in the lab focus on defining the roles of specific subpopulations of neuronal and non-neuronal cells to pain sensation, defining the role of RNA binding proteins in the development and maintenance of neuropathic pain, and understanding how rare skin diseases known as palmoplantar keratodermas lead to severe pain in the hands and feet.

Michael Matunis Lab
Research in the Michael Matunis Lab focuses on the SUMO family of small ubiquitin-related proteins. We study the covalent conjugation of SUMOs to other cellular proteins, which regulates numerous processes needed for cell growth and differentiation, and which, when defective, can lead to conditions such as cancer, neurodegenerative disease and diabetes.

Seth Blackshaw Lab
The Seth Blackshaw Lab uses functional genomics and proteomics to rapidly identify the molecular mechanisms that regulate cell specification and survival in both the retina and hypothalamus. We have profiled gene expression in both these tissues, from the start to the end of neurogenesis, characterizing the cellular expression patterns of more than 1,800 differentially expressed transcripts in both tissues. Working together with the lab of Heng Zhu in the Department of Pharmacology, we have also generated a protein microarray comprised of nearly 20,000 unique full-length human proteins, which we use to identify biochemical targets of developmentally important genes of interest.

Steven Claypool Lab
Research in the Claypool Lab is focused on defining how lipids and membrane proteins interact to establish and maintain normal mitochondrial function and how derangements in this complex relationship result in pathophysiology. We have demonstrated that yeast lacking tafazzin recapitulates all of the phospholipid abnormalities observed in human patients and many of the mitochondrial defects.
Another major project in our lab focuses on the mitochondrial ADP/ATP carrier that is required for oxidative phosphorylation. Researchers are studying how these novel interactions help establish normal mitochondrial function, the biochemical details of these associations, and whether disturbances in these assemblies can contribute to mitochondrial dysfunction. -
The Halushka Lab
The Halushka laboratory is interested in the overarching question of expression localization in tissues. To address this, the laboratory has set out upon several avenues of discovery in the areas of microRNA expression, proteomics and tissue gene expression. Many of these queries relate to the cardiovascular field as Dr. Halushka is a cardiovascular pathologist. Come learn about the science being done in the laboratory.

Tom Woolf Lab
The Tom Woolf Lab studies the quarter of the genome devoted to membrane proteins. This rapidly growing branch of bioinformatics, which includes computational biophysics, represents the main research direction of our group. We aim to provide insight into critical issues for membrane systems. In pursuit of these goals, we use extensive computer calculations to build an understanding of the relations between microscopic motions and the world of experimental measurements. Our calculations use our own Beowulf computer cluster as well as national supercomputer centers. An especially strong focus has been on the computed motions of proteins and all-atom models of the lipid bilayers that mediate their influence. To compute these motions, we use the molecular dynamics program CHARMM. We hope to use our understanding of the molecular motions for the prediction of membrane protein structures using new computational methods.

Zachara Lab
Elevation of O-GlcNAc levels modulates numerous pathways in a manner consistent with increased cell survival, including the expression of heat shock proteins. The Zachara Lab's goal is to understand the O-GlcNAc regulated stress response, how this can be manipulated to improve patient outcome and how this response is misregulated in disease.
-
Zhu Lab
The Zhu lab is focused on characterizing the activities of large collection of proteins, building signaling networks for better understanding the mechanisms of biological processes, and identifying biomarkers in human diseases and cancers.
More specifically, our group is interested in analyzing protein posttranslational modifications, and identifying important components involved in transcription networks and host-pathogen interactions on the proteomics level, and biomarkers in human IBD diseases.
