Selective targeting of MAPK family kinases JNK over p38 by rationally designed peptides as potential therapeutics for neurological disorders and epilepsy.

Human mitogen-activated protein kinase (MAPK) family members JNK and p38 are two homologous protein-serine/threonine kinases but play distinct roles in the pathological process of neurological disorders. Selective targeting of JNK over p38 has been established as a potential therapeutic approach to epilepsy and other nervous system diseases. Herein, we describe an integrated in vitro-in silico protocol to rationally design kinase-peptide interaction specificity based on crystal structure data.
