Crystal Structure of the Complex of Human Epidermal Growth Factor and Receptor Extracellular Domains.

The structure was published by Ogiso, H., Ishitani, R., Nureki, O., et al., Inoue, M., Shirouzu, M., and Yokoyama, S., in 2002 in a paper entitled "Crystal Structure of the Complex of Human Epidermal Growth Factor and Receptor Extracellular Domains." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.3 Å and deposited in 2002.

The experimental data on which the structure is based was not 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 most likely forms heterotetramers.
