DUSP6 (Dual Specificity Phosphatase 6), also known as MKP3 (Mitogen-Activated Protein Kinase Phosphatase 3), is a dual-specificity phosphatase that specifically dephosphorylates and inactivates ERK1/2. Unlike other DUSP family members, DUSP6 shows high specificity for ERK and is nuclear-excluded, acting in the cytoplasm to restrict ERK signaling. DUSP6 is induced by FGF (Fibroblast Growth Factor) and plays important roles in development and tissue homeostasis. In the nervous system, DUSP6 regulates neuronal differentiation and synaptic plasticity. Dysregulated DUSP6 expression has been implicated in cancer and may affect MAPK signaling in neurodegenerative diseases.
DUSP6 encodes MKP3, a dual-specificity phosphatase that specifically dephosphorylates and inactivates ERK1/2. MKP3 is a nuclear ERK phosphatase that provides feedback control of MAPK signaling. It is expressed in brain regions involved in learning and memory.
High expression in brain (hippocampus, cortex), heart, and lung.
| 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 |
