Research Description

My research goal is to develop chemical biology technologies and small molecules that will probe the biophysical/biochemical or cellular factors that regulate protein aggregation to elucidate the molecular mechanisms underlying their toxicity and functions. This will lead to the invention of new therapeutic / diagnostic / imaging strategies for the protein aggregation-associated diseases such as Alzheimer’s disease, Parkinson’s disease and particular cancers. In project 1, we will develop a novel target-specific chemical labeling technology by which the dynamic interactomes of a target protein can be identified with temporal resolution. Comparison of interactomes under various pathological conditions will reveal disease-associated interactomes. In project 2, we will develop a tool to detect different aggregation assembly states in amyloidogenesis pathways. This will be accomplished by identifying distinct sets of ligands (ligandome) that bind to different aggregation assembly states by high-throughput screening of combinatorial chemical libraries. Comparing ligandomes between healthy and diseased samples will lead to an understanding of physiological conditions under which toxic or functional aggregates are formed.
