== Publication Abstract from PubMed == | |||
MAPKs engage substrates, MAP2Ks, and phosphatases via a docking groove in the C-terminal domain of the kinase. Prior crystallographic studies on the unphosphorylated MAPKs p38alpha and ERK2 defined the docking groove and revealed long-range conformational changes affecting the activation loop and active site of the kinase induced by peptide. Solution NMR data presented here for unphosphorylated p38alpha with a MEK3b-derived peptide (p38alpha/pepMEK3b) validate these findings. Crystallograhic data from doubly phosphorylated active p38alpha (p38alpha/T *GY */pepMEK3b) reveal a structure similar to unphosphorylated p38alpha/MEK3b, and distinct from phosphorylated p38gamma (p38gamma/T *GY *) and ERK2 (ERK2/T *EY *). The structure supports the idea that MAP kinases adopt three distinct conformations: unphosphorylated, phosphorylated, and a docking peptide-induced form. | |||
