  • Genetic polymorphisms in drug metabolizing cytochrome P450 (CYP) enzymes are important determinants of inter-individual variability in drug response leading to adverse drug reactions and drug-drug interactions.  Despite the abundant structural and functional information available regarding multiple human CYPs, the structural basis of single nucleotide polymorphism has remained scant.  Using X-ray crystallography, biophysical and computational methods, the long-term goal of my research include studying the influence of genetic polymorphisms on the activity of CYPs.  Current research is focused on CYP2C9 variants.
  • Out of the 57 human CYPs, a number of enzymes have been designated as “orphans” since their functional role and specific substrates are unknown.  Another research interest of the lab is to characterize CYPs with unknown endogenous substrates or functions.  The research involves studying structure and function of CYP2U1.
