Crystal structure of the Grb14 BPS region in complex with the insulin receptor tyrosine kinase

The structure was published by Depetris, R.S., Hu, J., Gimpelevich, I., Holt, L.J., Daly, R.J., and Hubbard, S.R., in 2005 in a paper entitled "Structural basis for inhibition of the insulin receptor by the adaptor protein grb14." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.2 Å and deposited in 2005.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Insulin receptor and Growth factor receptor-bound protein 14.

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.
