'''THE STRUCTURE OF THE MAP KINASE P38 AT 2.1 ANGSTOMS RESOLUTION'''
===THE STRUCTURE OF THE MAP KINASE P38 AT 2.1 ANGSTOMS RESOLUTION===




==Overview==
<!--
The structure of mitogen-activated protein (MAP) kinase p38 has been solved at 2.1-A to an R factor of 21.0%, making p38 the second low activity MAP kinase solved to date. Although p38 is topologically similar to the MAP kinase ERK2, the phosphorylation Lip (a regulatory loop near the active site) adopts a different fold in p38. The peptide substrate binding site and the ATP binding site are also different from those of ERK2. The results explain why MAP kinases are specific for different activating enzymes, substrates, and inhibitors. A model presented for substrate and activator interactions has implications for the evolution of protein kinase cascades.
The line below this paragraph, {{ABSTRACT_PUBMED_9122194}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 9122194 is the PubMed ID number.
