Watching the inner life of a cell
Cellular processes are orchestrated by a large number of biomolecules in a spatially and temporally coordinated manner within a tiny volume. To uncover the underlying organizational principles and their functional relevance, we take microscopy visualization as the primary approach to systematically map the spatial localization, temporal dynamics and activity profiles of proteins and nucleic acids.
We are particularly interested in the following problems:
- Subcellular, high-resolution and dynamic mapping of the entire proteome,
- Physical organization and dynamics of the nucleus and the genome,
- Architecture of large protein complexes such as the ciliary transition zone, and
- Subcellular compartmentalization of signaling molecules, particularly
in the G-protein coupled receptor (GPCR) and receptor tyrosin kinase (RTK) signaling pathway, and how this spatial distribution defines signaling specificity.
In order to study these systems, we are developing the following microscopy technologies:
- Super-resolution and light-sheet microscopes that can visualize subcellular structures at a higher spatial resolution, record long term cell behavior, and track cells in intact animals, and
- New fluorescent probes and gene editing methods for the labeling of
and its applications
