TRAF2 and NCK-interacting protein kinase (TNIK)

TRAF2 and NCK-interacting protein kinase (TNIK) is a serine/threonine protein kinase encoded by the TNIK gene in humans. It is a member of the germinal center kinase (GCK) family, sharing structural features including an N-terminal kinase domain and a C-terminal regulatory domain. TNIK plays a central role in intracellular signaling, notably as a key regulator of the Wnt signaling pathway via phosphorylation of TCF4 and modulation of β-catenin activity. TNIK is ubiquitously expressed and implicated in processes such as cytoskeletal rearrangement, signal transduction, gene transcription, neuronal development, and stem cell maintenance. It has emerging importance as a therapeutic target in oncology, particularly in colorectal cancer, hematological malignancies (such as multiple myeloma), and other disease areas including fibrosis and neurological disorders. Pharmacological inhibition (e.g., by dovitinib) reduces cancer cell proliferation and induces apoptosis by suppressing Wnt-mediated transcriptional programs.
