The transmembrane (TM) and juxtamembrane (JM) regions of the epidermal growth factor receptor (EGFR) couple ligand binding in the extracellular domain to activation of the kinase domain. Solid-state NMR and polarized FTIR measurements of peptides corresponding to the TM plus JM regions of EGFR (residues 622-660) reconstituted in model phospholipid membranes are presented to address the role of the short cytoplasmic JM sequence (residues 645-660) in regulating EGFR activity. We show that the TM domain is helical with a transition to non-helical structure at the TM-JM boundary. Fluorescence measurements indicate that the JM region of EGFR(622-660) binds to the membrane surface and that binding can be reversed by the addition of the complex of Ca2+ and calmodulin. Together these data support models suggesting the cytoplasmic JM region of EGFR plays an active role in regulating receptor activity.
