MAP3K3 (Mitogen-Activated Protein Kinase Kinase Kinase 3), also known as MEKK3, is a serine/threonine kinase that activates the ERK, JNK, and p38 MAPK pathways. MAP3K3 is activated by various extracellular signals including growth factors, cytokines, and cellular stress. It plays critical roles in embryonic development, particularly of the cardiovascular and nervous systems. In neurons, MAP3K3 signaling contributes to synaptic plasticity and survival. Dysregulated MAP3K3 activity is implicated in neurodegenerative processes.
MAP3K3 encodes MEKK3, a serine/threonine kinase that activates both NF-κB and MAPK pathways. MEKK3 is essential for embryonic development and regulates cell proliferation, differentiation, and stress responses.
Widely expressed, with high expression in brain.
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| Alzheimer's Disease | Altered expression, rare variants | - | Dysregulated MAPK signaling affects tau phosphorylation, amyloid processing, synaptic plasticity |
| Parkinson's Disease | Altered expression | - | Contributes to neuronal death and protein aggregation |
| Various | See specific diseases | - | Role in cell survival and stress response |
