Crystal structure of X. tropicalis Spred1 EVH-1 domain
Overview
The recently described Spred protein family has been implicated in the modulation of receptor tyrosine kinase signalling. We report the crystal structure of the Enabled/vasodilator-stimulated phosphoprotein homology-1 (EVH1) domain from Xenopus tropicalis Spred1, solved to 1.15 A resolution. This structure confirms that the Spred EVH1 adopts the pleckstrin-homology fold, with a similar secondary structure to Enabled. A translation of one of the peptide-binding groove beta-strands narrows this groove, whilst one end of the groove shows structural flexibility. We propose that Spred1 will bind peptides that are less proline-rich than other EVH1 domains, with conformational changes indicating an induced fit.
