[MWClarkson blog] Dynamic origins of PBX1 homeodomain allostery
Dynamic origins of PBX1 homeodomain allostery
http://www.researchblogging.org/public/citation_icons/rb2_large_gray.pngIn the Monod-Wyman-Changeux model for cooperative binding, proteins exist in an equilibrium of low-affinity and high-affinity states in solution, absent any ligand. In this view, although it may appear that the binding of a ligand causes a conformational transition, it actually stabilizes one conformation from a pre-existing equilibrium. In the past several years, advanced NMR techniques have yielded increasing evidence that these structural equilibria exist for a number of...

Authors: Fraenkel E, Pabo CO
Homeodomains are one of the key families of eukaryotic DNA-binding motifs and provide an important model system for studying protein-DNA interactions. We have crystallized the Antennapedia homeodomain-DNA complex and solved this structure at 2.4 A resolution. NMR and molecular dynamics studies...
