TRAF2- and NCK-interacting kinase (TNIK)

TRAF2- and NCK-interacting kinase (TNIK) is a serine/threonine protein kinase. It is a member of the germinal center kinase (GCK) family and plays critical roles in several cellular processes, including signal transduction, gene transcription regulation, cytoskeletal organization, and cell proliferation. TNIK acts as an essential activator of the Wnt signaling pathway and regulates cytoskeletal dynamics. Dysregulation or overexpression of TNIK has been implicated in various cancers. Inhibitors targeting TNIK have shown promise for anti-cancer therapy. There is also evidence supporting its involvement in pulmonary fibrosis pathogenesis.

Dovitinib: Multi-targeted tyrosine kinase inhibitor that suppresses TNIK function at nanomolar concentrations, leading to reduced cancer cell viability through apoptosis induction. KY‑05009: Potent inhibitor with IC₅₀ ~9 nM against TNIK activity; blocks β-catenin/TCF4-mediated transcriptional activity. Mechanism-of-action studies show these inhibitors block ATP binding at the active site or disrupt key protein-protein interactions necessary for downstream signal propagation.
