摘要: The structure of the MAP kinase ERK2, a ubiquitous protein target for regulation by Ras and Raf, has been solved in its unphosphorylated low-activity conformation to resolution 2.3 A. two domains ERK2 are farther apart than active cAMP-dependent peptide-binding site is blocked tyrosine 185, one residues that phosphorylated enzyme. Activation thus likely involve both global local conformational changes.
