JAK1 is a non-receptor tyrosine kinase with a FERM domain for receptor binding, an SH2-like domain, a pseudokinase (JH2) domain with regulatory function, and a kinase (JH1) domain with catalytic activity. The JH2 domain acts as an autoinhibitory module, preventing constitutive activation. JAK1 associates with cytokine receptors through its FERM domain. Upon ligand binding and receptor dimerization, JAKs trans-activate and phosphorylate receptor tyrosine residues.
In the CNS, JAK1 mediates signaling for multiple cytokines:
| Disease | Role | Mechanism |
|---|---|---|
| Alzheimer's Disease | Risk factor | Enhanced JAK1-STAT3 signaling promotes chronic neuroinflammation |
| Parkinson's Disease | Risk factor | Dysregulated cytokine signaling in dopaminergic neurons |
| ALS | Risk factor | Enhanced inflammatory responses through JAK1 |
| Multiple Sclerosis | Therapeutic target | JAK inhibitors reduce disease activity |
