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.
High expression in immune cells (microglia, macrophages, T cells). Moderate expression in neurons and astrocytes. Constitutively expressed in most cell types.
