GLYCOGEN SYNTHASE KINASE 3 BETA COMPLEXED WITH AXIN PEPTIDE

Overview

Glycogen synthase kinase 3beta (GSK3beta) is a serine/threonine kinase, involved in insulin, growth factor and Wnt signalling. In Wnt signalling, GSK3beta is recruited to a multiprotein complex via interaction with axin, where it hyperphosphorylates beta-catenin, marking it for ubiquitylation, and destruction. We have now determined the crystal structure of GSK3beta, in complex with a minimal GSK3beta-binding segment of axin, at 2.4 A, resolution. The structure confirms the co-localization of the binding, sites for axin and FRAT in the C-terminal domain of GSK3beta, but reveals, significant differences in the interactions made by axin and FRAT, mediated by conformational plasticity of the 285-299 loop in GSK3beta., Detailed comparison of the axin and FRAT GSK3beta complexes allows the, ...
