The structure of p38 alpha in complex with a dihydroquinolinone

The structure was published by Fitzgerald, C.E., Patel, S.B., Becker, J.W., et al., Pikounis, V.B., O'Keefe, S.J., and Scapin, G., in 2003 in a paper entitled "Structural basis for p38alpha MAP kinase quinazolinone and pyridol-pyrimidine inhibitor specificity" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2003.

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 348 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.
