Crystal structure of ErbB4/HER4 extracellular domain

The structure was published by Bouyain, S., Longo, P.A., Li, S., Ferguson, K.M., and Leahy, D.J., in 2005 in a paper entitled "The extracellular region of ErbB4 adopts a tethered conformation in the absence of ligand" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.396 Å and deposited in 2005.

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

This PDB entry contains multiple copies of the structure of Receptor tyrosine-protein kinase erbB-4.

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.
