Current Research:
|
My laboratory has been studying the E. coli virus, lambda, and its relatives. Our focus has been the inhibition of lambda gene expression by phage HK022 Nun protein. Nun binds to specific sequences in lambda nascent mRNA and blocks translocation of RNA polymerase. Nun also contacts lambda DNA template just promoter-distal to the stalled RNA polymerase. Nun binds Zn++ and may coordinate this ion with RNA polymerase. Genetic, biochemical and structural studies of this unusual reaction are underway.
The subcellular location of PKA is of critical importance in transmission of cAMP signals. How PKA anchoring proteins (AKAPs) affects cAMP signal transduction is being investigated in cultured cell lines.
