Disease

[MK10_HUMAN] Defects in MAPK10 are a cause of epileptic encephalopathy Lennox-Gastaut type (EELG) [MIM:606369]. Epileptic encephalopathies of the Lennox-Gastaut group are childhood epileptic disorders characterized by severe psychomotor delay and seizures. Note=A chromosomal aberration involving MAPK10 has been found in a single patient. Translocation t(Y;4)(q11.2;q21) which causes MAPK10 truncation.

Function

[MK10_HUMAN] Serine/threonine-protein kinase involved in various processes such as neuronal proliferation, differentiation, migration and programmed cell death. Extracellular stimuli such as proinflammatory cytokines or physical stress stimulate the stress-activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) signaling pathway. In this cascade, two dual specificity kinases MAP2K4/MKK4 and MAP2K7/MKK7 phosphorylate and activate MAPK10/JNK3. In turn, MAPK10/JNK3 phosphorylates a number of transcription factors, primarily components of AP-1 such as JUN and ATF2 and thus regulates AP-1 transcriptional activity. Plays regulatory roles in the signaling pathways during neuronal apoptosis. Phosphorylates the neuronal microtubule regulator STMN2. Acts in the regulation of the beta-amyloid precursor protein/APP signaling during neuronal differentiation by phosphorylating APP. Participates also in neurite growth in spiral ganglion neurons.^[1]

Publication Abstract from PubMed

We target the gatekeeper MET146 of c-Jun N-terminal kinase 3 (JNK3) to exemplify the applicability of X...S halogen bonds in molecular design using computational, synthetic, structural and biophysical techniques. In a designed series of aminopyrimidine-based inhibitors, we unexpectedly encounter a plateau of affinity. Compared to their QM-calculated interaction energies, particularly bromine and iodine fail to reach the full potential according to the size of their sigma-hole. Instead, mutation of the gatekeeper residue into leucine, alanine, or threonine reveals that the heavier halides can significantly influence selectivity in the human kinome. Thus, we demonstrate that, although the choice of halogen may not always increase affinity, it can still be relevant for inducing selectivity. Determining the crystal structure of the iodine derivative in complex with JNK3 (4X21) reveals an unusual bivalent halogen/chalcogen bond donated by the ligand and the back-pocket residue MET115. Incipient repulsion from the too short halogen bond increases the flexibility of Cepsilon of MET146, whereas the rest of the residue fails to adapt being fixed by the chalcogen bond. This effect can be useful to induce selectivity, as the necessary combination of methionine residues only occurs in 9.3% of human kinases, while methionine is the predominant gatekeeper (39%).
