Two-component systems in Arabidopsis thaliana - A structural view

Plants respond to outside stimuli by initiating signaling cascades that regulate gene expression. Little structural information is available on the signaling proteins that are part of the two-component systems of plants, and how changes in phosphorylation translate into alterations of three-dimensional structures and changes in recognition domains remains largely mysterious. Our work is on deciphering aspects of these systems through the crystallization and structural analysis of two-component system proteins in Arabidopsis thaliana. (C) 2009 Elsevier GmbH.
