The primary goal of the Department of Structural Biology at St. Jude is to understand life and disease at the atomic level.
We use sophisticated biophysical techniques — such as Nuclear Magnetic Resonance (NMR) spectroscopy, X-ray crystallography, cryo-electron microscopy and tomography, single-molecule imaging, and mass spectrometry — to determine the three-dimensional structures and dynamics of biological macromolecules. These experimental methods are combined with computational and data-science approaches, to provide insight into how macromolecules move, alter their structures and interact with other molecules, in order to carry out their biological functions. Such integrative studies expand our understanding of the most fundamental biological processes and of the diseases that arise when those processes go awry.
Researchers in our department are working to decipher the biophysical principles and molecular details of key cellular processes, including gene expression, subcellular organization, oncogenesis, protein translation, protein folding and misfolding, fatty acid biosynthesis, membrane transport, signaling and cell death. Atomic-level information of proteins and macromolecular complexes provide fundamental insights and can help design new therapeutics, materials and diagnostic tools.
The Technology Core Centers at the Structural Biology Department provide investigators with access to cutting-edge equipment and methodologies. Each Center is managed by dedicated staff scientists who provide training and support to researchers investigating structure–function of proteins and of macromolecular complexes. With in-house scientific expertise and state-of-the-art facilities, the Centers enable the combination of multiple approaches to tackle challenging biological problems, thus empowering integrative structural biology.
