Courses Taught

BIOC5240Q   Molec Biol of the News

BIOC5240 Molecular Biology of the News. 1 cr. Spring -- only occurs in Spring of odd years (2009, 2011 etc). The objective of this course is to discuss fundamental biochemical principles underlying recent developments that have received attention in the lay press (e.g., New York Times, Time Magazine).


Current Research

HCV-host cell interaction.
The molecular mechanisms that establish chronic HCV infection and cause its subsequent progression to LC and HCC are poorly understood. Recently, using affinity capture and LC/MS/MS approach, we identified numerous cellular factors associated with the HCV genome; many of these were shown to be essential for HCV replication. One of the proteins that we identified is FUSE binding protein (FBP) which is abundantly expressed in LC and HCC with hepatitis C background. FBP interacts with various proapoptotic and anti-apoptotic cellular factors and facilitates persistent HCV replication. Currently we are investigating the molecular mechanism of these interactions and their implication on HCV replication.

Structure-function relationship in HIV-1 reverse transcriptase.
Until recently, only the N-terminal polymerase domain of HIV-1 RT, corresponding to 1-321 amino acid residues, was considered to be the primary site of specific mutational changes leading to the emergence of drug-resistant strains. However, studies have now implicated both the connection subdomain (residues 322-440) and RNase H domain (residues 441-560) in the emergence of drug-resistant strains of HIV-1, in spite of their distal location from the polymerase active site. Several mechanisms have been proposed to explain how mutational changes in the connection subdomain (CN) and RNase H (RNH) domain may confer drug resistance on the enzyme. One potential mechanism that has not been explored thus far is that the C-terminal of RNH interacting with the CN may be structurally important in subunit dimerization or dimer stability of the enzyme. This hypothesis is supported by the fact that a hydrophobic cluster in the CN encompassing residues W398, W401, W402, Y405, W406, W410, and W414 has an important role in RT dimerization. Our current focus is to identify specific motif /amino acid residues in RNase H domain that play crucial role in in dimerization of HIV-1 RT.
