Crystal Structure of Unactivated APO Insulin-like Growth Factor-1 Receptor Kinase Domain

The structure was published by Munshi, S., Kornienko, M., Hall, D.L., et al., Stirdivant, S.M., Darke, P.L., and Kuo, L.C., in 2002 in a paper entitled "Crystal structure of the Apo, unactivated insulin-like growth factor-1 receptor kinase. Implication for inhibitor specificity." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.7 Å and deposited in 2002.

The experimental data on which the structure is based was not deposited.
