We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| + | c-Jun N-terminal kinase (JNK) 2 is a member of the mitogen-activated protein (MAP) kinase group of signaling proteins. MAP kinases share a common sequence insertion called "MAP kinase insert", which, for ERK2, has been shown to interact with regulatory proteins and, for p38alpha, has been proposed to be involved in the regulation of catalytic activity. We have determined the crystal structure of human JNK2 complexed with an indazole inhibitor by applying a high-throughput protein engineering and surface-site mutagenesis approach. A novel conformation of the activation loop is observed, which is not compatible with its phosphorylation by upstream kinases. This activation inhibitory conformation of JNK2 is stabilized by the MAP kinase insert that interacts with the activation loop in an induced-fit manner. We therefore suggest that the MAP kinase insert of JNK2 plays a role in the regulation of JNK2 activation, possibly by interacting with intracellular binding partners. | ||
