Structure of the Oncoprotein DEK: a putative DNA-binding Domain Related to the Winged Helix Motif
Contents |
Overview
The chromatin-associated protein DEK was first identified as a fusion, protein in patients with a subtype of acute myelogenous leukemia. It has, since become associated with diverse human ailments ranging from cancers, to autoimmune diseases. Despite much research effort, the biochemical, basis for these clinical connections has yet to be explained. We have, identified a structural domain in the C-terminal region of DEK, [DEK(309-375)]. DEK(309-375) implies clinical importance because it can, reverse the characteristic abnormal DNA-mutagen sensitivity in fibroblasts, from ataxia-telangiectasia (A-T) patients. We determined the solution, structure of DEK(309-375) by nuclear magnetic resonance spectroscopy, and, found it to be structurally homologous to the E2F/DP transcription factor, family. On the basis of this homology, we tested whether DEK(309-375), could bind DNA and identified the DNA-interacting surface. DEK presents a, hydrophobic surface on the side opposite the DNA-interacting surface. The, structure of the C-terminal region of DEK provides insights into the, protein function of DEK.
