Research interests
Macromolecular protein complexes exhibit highly dynamic structures and functions that depend on the physiological state of the cell. These complexes play fundamental roles in basic life processes including protein translation, cell division, cellular trafficking, and inflammation. The Zhu Lab at Case Western Reserve University is interested in the structure and function of these critical complexes. We utilize cryo-electron tomography (cryo-ET), an advancing imaging technique, to determine the three-dimensional structure of these complexes in the native cellular context. The in situ structure has proven challenging but promised to provide essential structural information of critical biological relevance.
The Zhu Lab participated in the installation and validation of the Aquilos 2 cryo-FIB/SEM in CWRU. The lab has been using the Aquilos 1 since 2018 and produced its first high-quality in situ cryo-ET study in 2019 using the Aquilos 1, published in Nature in 2021 (PMID: 34040255)
In situ cryo-correlative light and electron microscopy (cryo-CLEM) for precise ROI identification before and after cryo-FIB milling. This system in CWRU was the third of its kind installed and validated in the United States by the Zhu Lab.
A state-of-the-art 300 kV cryogenic TEM for high-resolution structural visualization using cryo-ET. Cryo-ET data-collection scripts have been installed, optimized, and validated by the Zhu Lab.
We have direct access to cryo-FIB/SEM, Cryo-CLEM, and Titan Krios TEM to perform advancing cryo-electron tomography studies at CWRU.
