JNK3 (human)

Overview
JNK3 a protein kinase of the MAPK family that is potently activated by a variety of environmental stress and pro-inflammatory cytokines. Brain-selective JNK isoform. A pro-apoptotic protein and potential tumor suppressor. Phosphorylates a number of transcription factors including c-Jun, ATF2 and ELK1. Required for stress-induced neuronal apoptosis and the pathogenesis of glutamate excitotoxicity. CDK5 can phosphorylate and inhibit the activity of this kinase, which may be important in preventing neuronal apoptosis. Binds to at least four scaffolding proteins, JIP-1, -2, -3 and -4. Interacts with HDAC9. Expression lost in brain tumors. May function in neuronal cell death from injury and neurodegeneration, for which inhibitors are being developed. Two alternatively spliced transcript variants have been reported. Note: This description may include information from UniProtKB.
