Crystal structure of the insulin receptor kinase in complex with IRS2 KRLB peptide and ATP

The structure was published by Wu, J., Tseng, Y.D., Xu, C.F., Neubert, T.A., White, M.F., and Hubbard, S.R., in 2008 in a paper entitled "Structural and biochemical characterization of the KRLB region in insulin receptor substrate-2." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2007.

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

This PDB entry contains a complex of 2 biomacromolecules, namely insulin receptor subunit beta and Insulin receptor substrate 2.

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.
