Crystal Structure of p38a Mitogen-Activated Protein Kinase in Complex with a Pyrazolopyridinone Inhibitor.

The structure was published by Pettus, L.H., Wurz, R.P., Xu, S., et al., Mohr, C., Hsieh, F., and Tasker, A.S., in 2010 in a paper entitled "Discovery and evaluation of 7-alkyl-1,5-bis-aryl-pyrazolopyridinones as highly potent, selective, and orally efficacious inhibitors of p38alpha mitogen-activated protein kinase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.31 Å and deposited in 2010.

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

The PDB entry contains the structure of Mitogen-activated protein kinase 14. This molecule has the UniProt identifier Q16539 (MK14_HUMAN)search. The sample contained 366 residues which is 100% of the natural sequence. Out of 366 residues 341 were observed and are deposited in the PDB.

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 is most likely monomeric.
