TYK2 is a non-receptor tyrosine kinase belonging to the Janus kinase family. Like other JAKs, it contains a FERM domain for receptor binding, an SH2-like domain, a pseudokinase (JH2) domain, and a kinase (JH1) domain. TYK2 is unique among JAKs in its ability to couple with multiple cytokine receptors, including type I IFN receptors, IL-10 family receptors, and IL-12 family receptors. The JH2 domain maintains an inactive conformation in the absence of ligand.
TYK2 mediates several signaling pathways in the CNS:
| Disease | Role | Mechanism |
|---|---|---|
| Alzheimer's Disease | Risk factor | TYK2 promotes chronic neuroinflammation through type I IFN signaling |
| Parkinson's Disease | Risk factor | Altered cytokine signaling affects dopaminergic neuron survival |
| Multiple Sclerosis | Therapeutic target | TYK2 inhibitors reduce inflammatory demyelination |
| ALS | Risk factor | Enhanced inflammatory responses |
