STRUCTURE OF THE SECOND EPS15 HOMOLOGY DOMAIN OF HUMAN EPS15, NMR, 20 STRUCTURES
Overview
Eps15 homology (EH) domains are eukaryotic signaling modules that, recognize proteins containing Asn-Pro-Phe (NPF) sequences. The structure, of the central EH domain of Eps15 has been solved by heteronuclear, magnetic resonance spectroscopy. The fold consists of a pair of EF hand, motifs, the second of which binds tightly to calcium. The NPF peptide is, bound in a hydrophobic pocket between two alpha helices, and binding is, mediated by a critical aromatic interaction as revealed by structure-based, mutagenesis. The fold is predicted to be highly conserved among 30, identified EH domains and provides a structural basis for defining, EH-mediated events in protein trafficking and growth factor signaling.
