Research Description:

My lab mainly studies the biochemistry of viral proteins and small molecules that interact with them. Our main interest, presently, is in targeting a helicase encoded by the hepatitis C virus (HCV). 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 other helicases from related viruses and human cells, and other viral proteins such as polymerases, proteases and capsid proteins. The goal of most projects in the lab is either to understand how these proteins help copy viral genomes or to understand how small molecule drugs block virus growth by directly interfering with these important enzymes.
