1s9i Summary


X-ray structure of the human mitogen-activated protein kinase kinase 2 (MEK2)in a complex with ligand and MgATP

The structure was published by Ohren, J.F., Chen, H., Pavlovsky, A., et al., Barrett, S., Tecle, H., and Hasemann, C.A., in 2004 in a paper entitled "Structures of human MAP kinase kinase 1 (MEK1) and MEK2 describe novel noncompetitive kinase inhibition." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.2 Å and deposited in 2004.

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