Solution NMR insights into docking interactions involving inactive ERK2.

ABSTRACT: The mitogen-activated protein (MAP) kinase ERK2 contains recruitment sites that engage canonical and noncanonical motifs found in a variety of upstream kinases, regulating phosphatases and downstream targets. Interactions involving two of these sites, the D-recruitment site (DRS) and the F-recruitment site (FRS), have been shown to play a key role in signal transduction by ERK/MAP kinases. The dynamic nature of these recruitment events makes NMR uniquely suited to provide significant insight into these interactions. While NMR studies of kinases in general have been greatly hindered by their large size and complex dynamic behavior leading to the suboptimal performance of standard methodologies, we have overcome these difficulties for inactive full-length ERK2 and obtained an acceptable leve
