Introduction
Jak1 — Janus Kinase 1 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
JAK1 encodes Janus kinase 1, a non-receptor tyrosine kinase that mediates signaling for type I and type II cytokine receptors. JAK1 is essential for signaling by interferons (IFN-α, IFN-β, IFN-γ), interleukins (IL-2, IL-4, IL-6, IL-10, IL-12, IL-23), and other cytokines. Upon ligand binding, JAK1 phosphorylates cytokine receptors, creating docking sites for STAT proteins. JAK1 then phosphorylates STATs, which dimerize and translocate to the nucleus. In the brain, JAK1 regulates neuroinflammation, microglial activation, and neuronal survival.
Expression
High expression in immune cells ([microglia](/cell-types/microglia-neuroinflammation), macrophages, T cells). Moderate expression in [neurons](/entities/neurons) and [astrocytes](/entities/astrocytes). Constitutively expressed in most cell types.
