DUSP1 (Dual Specificity Phosphatase 1), also known as MKP1 (Mitogen-Activated Protein Kinase Phosphatase 1), is a dual-specificity phosphatase that dephosphorylates and inactivates MAPK family members including ERK, JNK, and p38. DUSP1 is an immediate-early gene induced by cellular stress, growth factors, and hormones. It functions as a negative regulator of MAPK signaling, providing feedback control to prevent excessive or prolonged kinase activation. In neurons, DUSP1 regulates synaptic plasticity and neuronal survival. Altered DUSP1 expression is observed in Alzheimer's disease and Parkinson's disease, where it may represent a compensatory mechanism against dysregulated MAPK signaling.
DUSP1 encodes MKP1, a dual-specificity phosphatase that dephosphorylates and inactivates ERK, JNK, and p38 MAP kinases. MKP1 is an immediate-early gene induced by stress and glucocorticoids. It provides negative feedback to MAPK signaling and protects neurons from stress-induced apoptosis. Reduced DUSP1 expression is observed in AD brains.
Inducible in most tissues, including brain, upon stress stimuli.
| 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 |
