Exploring translocation of proteins on DNA by NMR
Exploring translocation of proteins on DNA by NMR
Abstract While an extensive body of knowledge has accumulated on the structures of transcription factors, DNA and their complexes from both NMR and crystallography, much less is known at a molecular level regarding the mechanisms whereby transcription factors locate their specific DNA target site within an overwhelming sea of non-specific DNA sites. Indirect kinetic data suggested that three processes are involved in the search procedure: jumping by dissociation of the protein from the DNA followed by re-association at another site,...

NMR spectroscopy is one of the most powerful tools for the characterization of biomolecular systems. A unique aspect of NMR is its capacity to provide an integrated insight into both the structure and intrinsic dynamics of biomolecules. In addition, NMR can provide site-resolved information about the conformation entropy of binding, as well as about energetically excited...

Zif268 is a zinc-finger protein containing three Cys2-His2-type zinc-finger domains that bind the target DNA sequence GCGTGGGCG in a cooperative manner. In this work, we characterized translocation of the Zif268 protein between its target DNA sites using NMR spectroscopy. The residual dipolar coupling...

Postdoctoral position to study Protein-Protein Interactions and their role in Mechanisms of Signal Transduction using protein solution NMR /x-ray crystallography
Case Medical School, Cleveland, Ohio, USA
How are signaling events transmitted from one protein to another? To answer this question we are looking to add a postdoctoral co-workers to our interdisciplinary team. Our interest is to understand protein-protein interactions, protein structure and dynamics in the context of cell signaling...
