The receptor tyrosine kinase encoded by the neu/erbB-2 proto-oncogene is constitutively activated by a single valine to glutamic acid substitution at position 664 in the predicted membrane-spanning sequence of the receptor. We have explored the structural changes involved in receptor activation with polarized FTIR and magic angle spinning NMR spectroscopy. The hydrophobic transmembrane sequence folds into a well-defined α-helical structure spanning the membrane bilayer. Measurements of the pKa and 13C chemical shift anisotropy of Glu 664 reveal that the side chain carboxyl group is protonated and strongly hydrogen bonded. These studies provide direct evidence for glutamate hydrogen-bonding interactions in the mechanism of receptor dimerization and activation.
