The Extracellular and Transmembrane Domain Interfaces in Epidermal Growth Factor Receptor Signaling

The structure was published by Lu, C., Mi, L.Z., Grey, M.J., et al., Graef, E., Yokoyama, S., and Springer, T.A., in 2010 in a paper entitled "Structural evidence for loose linkage between ligand binding and kinase activation in the epidermal growth factor receptor." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.304 Å and deposited in 2010.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely Epidermal growth factor receptor and Epidermal growth factor.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule has more than one probable quaternary state observed. For more details see the quaternary structure page.
