Supplementary information

JNK3 also known as c-Jun N-terminal kinase 3 belongs to the mitogen-activated protein kinase (MAPK) family. It has a molecular weight of approximately 48 kDa. This protein is part of the signaling cascade that responds to stress stimuli such as cytokines and ultraviolet irradiation. JNK3 expression occurs mainly in the brain but some reports note its expression in the heart and pancreas as well.
Biological function summary

JNK3 performs critical functions in neuronal apoptosis and neurodegeneration. JNK3 is part of the MAPK signaling complex which regulates various cellular activities including gene expression and cell differentiation. Activation of JNK3 leads to the phosphorylation and activation of transcription factors like c-Jun which assist in controlling stress-induced cellular responses.

Pathways

Queries into MAPK pathways reveal significant involvement of JNK3 in the stress-activated protein kinase (SAPK) pathway. JNK3 interacts with proteins such as ASK1 and MKK4/7 serving as upstream kinases to modulate environmental stress responses. The pathway also relates to other MAPKs like ERK and p38 although they perform distinct functions within the signaling network.

JNK3 has strong connections to neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease. Dysregulation in JNK3 signaling leads to increased neuronal cell death aggravating disease pathology. In Alzheimer's disease JNK3 may interact with tau protein contributing to tau phosphorylation and neurofibrillary tangle formation. In Parkinson's disease JNK3 involvement in dopaminergic neuron apoptosis highlights its potential role in disease progression linking it further to key proteins implicated in neurodegeneration.

General info

Function

Serine/threonine-protein kinase involved in various processes such as neuronal proliferation, differentiation, migration and programmed cell death. Extracellular stimuli such as pro-inflammatory 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 amyloid-beta precursor protein/APP signaling during neuronal differentiation by phosphorylating APP. Also participates in neurite growth in spiral ganglion neurons. Phosphorylates the CLOCK-BMAL1 heterodimer and plays a role in the photic regulation of the circadian clock (PubMed : 22441692). Phosphorylates JUND and this phosphorylation is inhibited in the presence of MEN1 (PubMed : 22327296).

Sequence similarities

Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.

Post-translational modifications

Dually phosphorylated on Thr-221 and Tyr-223 by MAP2K4 and MAP2K7, which activates the enzyme. MAP2K7 shows a strong preference for Thr-221 while MAP2K4 phosphorylates Tyr-223 preferentially. Weakly autophosphorylated on threonine and tyrosine residues in vitro.. Palmitoylation regulates subcellular location and axonal development.
