RAF1 (c-Raf) is a serine/threonine protein kinase that serves as a critical intermediate in the RAS-RAF-MEK-ERK (MAPK) signaling cascade. Unlike its family member BRAF, RAF1 possesses both kinase-dependent and kinase-independent functions, allowing it to regulate diverse cellular processes including cell proliferation, differentiation, survival, and apoptosis. RAF1 is essential for neuronal development, synaptic plasticity, and cognitive function. Mutations in RAF1 are associated with developmental disorders including Noonan Syndrome and LEOPARD Syndrome, while dysregulated RAF1 signaling contributes to neurodegenerative diseases such as Alzheimer's and Parkinson's disease.
RAF1 (c-Raf) encodes a serine/threonine kinase that is a key component of the RAS-RAF-MEK-ERK pathway. Unlike BRAF, RAF1 has kinase-independent functions and can regulate apoptosis through interactions with BAD and caspase-9. RAF1 is essential for neuronal survival and synaptic plasticity.
Widely expressed, with high expression in brain, heart, and skeletal muscle.
| 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 |
The study of Raf1 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
