Structure of the Insulin-like Growth Factor 1 Receptor Kinase

The structure was published by Favelyukis, S., Till, J.H., Hubbard, S.R., and Miller, W.T., in 2001 in a paper entitled "Structure and autoregulation of the insulin-like growth factor 1 receptor kinase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2001.

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

This PDB entry contains a complex of 2 biomacromolecules, namely insulin-like growth factor 1 receptor and insulin receptor substrate 1.

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 heterodimers.
