Research Interests:
Macromolecular interaction, including protein-protein and protein-nucleic
acid plays critical roles in almost every signaling pathway. Recent
development of residual dipolar couplings (RDCs) in modem NMR spectroscopy
has extended its speed, accuracy and scope of structure determination.
Studies of these interactions by NMR may provide useful insight into
the function and mechanism of those macromolecules. Systems of primary
interest to us are protein-protein interactions involved in apoptosis
signaling, viral RNA translocation and viral budding pathways.
