Research Interests
My lab mainly studies the biochemistry of viral proteins and the small molecules that interact with them to discover new antiviral drugs. Our main interest, presently, is in targeting helicases encoded by:
- The hepatitis C virus (HCV)
- Dengue virus (DENV)
- West Nile Virus
- SARS-CoV-2
Helicases are motor proteins that separate DNA and RNA duplexes and dislodge proteins bound to nucleic acids in reactions fueled by ATP hydrolysis. We also study helicases from human cells and other viral proteins as drug targets, including polymerases, proteases, and capsid proteins. Most projects in the lab aim to understand how these proteins help copy viral genomes or how small-molecule drugs block viral growth by directly interfering with these enzymes.
Techniques used in our lab:
-
- Recombinant DNA technology
- Protein purification
- Enzymology
- Steady-state and transient-state kinetics
- Tissue Culture
- Fluorescence Microscopy
- Quantitative RT-PCR
- High-throughput screening
- Absorbance spectroscopy
- Fluorescence spectroscopy
- TR-FRET, alpha-screen and FP assays
- Biocalorimetry
- Molecular Modeling
