Target intelligence / Profile preview

Non-receptor tyrosine-protein kinase TYK2 (TYK2)

Target
TYK2
Molecular classification
Enzyme, Protein kinase, Janus kinase (JAK), Non-receptor tyrosine kinase
01

Overview

Non-receptor tyrosine-protein kinase TYK2 is a central regulator within multiple cytokine signaling pathways essential for immune system function. It acts through association with specific receptor complexes at the plasma membrane where it activates downstream effectors such as STATs via phosphorylation events triggered upon ligand binding.

Other names
Tyrosine kinase 2
02

Mechanism of action

TYK2 inhibitors block the kinase activity of TYK2, preventing downstream signaling cascades, particularly those involving STAT proteins. This modulates immune responses.
