Research Summary
The Lyu Lab focuses on investigating and modulating protein function, with particular interest in intrinsically disordered proteins, membrane proteins, protein folding, arginylation, and protein–protein interactions. We aim to develop small-molecule therapeutics, including covalent and non-covalent inhibitors, proteolysis-targeting chimeras (PROTACs), molecular glue degraders (MGDs), and other novel degraders and modulators, to target disease-associated proteins for the treatment of cancers and other diseases.
Impact on Patients in Georgia
The goal of our research is to develop small-molecule therapeutics to target disease-associated proteins.
We are particularly interested in proteins relating to the development and spread of cancers such as leukemias, breast cancer, lung cancer, and prostate cancer, as well as other disorders such as vascular, autoimmune, and neurodegenerative diseases.
Development of new therapeutics to treat these cancers and other disorders will eventually have a major impact on public health in Georgia, a state with a high prevalence of specific cancers (breast, prostate, lung) and cardiovascular diseases.
Research Projects

Hijacking Arginylation for Targeted Protein Degradation
Protein arginylation, catalyzed by ATE1, is an important post-translational modification that regulates protein stability and is implicated in cancer progression. We aim to identify arginylated proteins and their modification sites in cancer cells and to harness ATE1 for targeted protein degradation through a novel strategy called Arginylation Targeting Chimera (ArgTAC). This work may establish a new therapeutic platform for targeting cancer-driving proteins.

Drugging the Undruggable Proteome
Approximately 85% of the human proteome remains undruggable by conventional small-molecule approaches. Our lab develops innovative chemical biology platforms and targeted protein modulation strategies to expand the druggable proteome. We created polyHisTAC, a versatile tool to rapidly assess the degradability of challenging proteins and validate their suitability for PROTAC-based targeting. Using these platforms, we develop PROTACs, molecular glue degraders, and other targeted protein modulators to drug previously inaccessible disease-relevant proteins.
-
Caspase Cleavage Targeting Chimeras (CACTACs)
Caspases are proteases that cleave proteins to regulate cell death and other cellular processes. We are developing Caspase Cleavage Targeting Chimeras (CACTACs), a new modality that induces targeted protein cleavage by recruiting caspases to disease-relevant proteins. This approach provides a distinct way to rapidly disable protein function and may lead to new cancer therapies.
- Chemical Biology of Protein Arginylation
The biological functions of protein arginylation remain poorly understood. We develop and apply chemical biology, proteomics, and functional genomics approaches to identify arginylation sites and substrates, uncover their roles in cardiovascular biology and disease, and discover enzymes involved in de-arginylation. These studies will advance our understanding of arginylation and enable new strategies for therapeutic intervention.
