Introduction
Tyk2 — Tyrosine Kinase 2 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
TYK2 encodes tyrosine kinase 2, a non-receptor tyrosine kinase that belongs to the Janus kinase (JAK) family. TYK2 is a key component of type I and type III cytokine receptor signaling. It mediates signaling for interferons (IFN-α, IFN-β), IL-10, IL-12, and IL-23 receptors. TYK2 activation leads to STAT phosphorylation and downstream gene transcription. In the nervous system, TYK2 regulates neuroinflammation, microglial activation, and neuronal survival.
Expression
Widely expressed in immune cells including [microglia](/cell-types/microglia-neuroinflammation), macrophages, and lymphocytes. Lower expression in [neurons](/entities/neurons) and [astrocytes](/entities/astrocytes).
