TNK2 (tyrosine kinase non-receptor 2), also known as ACK1 (activated CDC42 kinase 1), is a non-receptor tyrosine kinase involved in diverse cellular signaling pathways. It plays a critical role in regulating cell proliferation, survival, migration, and cytoskeletal reorganization. Structurally, TNK2 contains a kinase domain, a SH3 domain, and a CDC42-binding domain, enabling interactions with signaling molecules like growth factor receptors (e.g., EGFR, HER2) and small GTPases (e.g., CDC42). Its activation often occurs downstream of extracellular stimuli, including growth factors or stress signals, triggering phosphorylation cascades that influence pathways such as PI3K/AKT, MAPK, and Wnt/β-catenin.
TNK2 has gained attention for its oncogenic potential. Overexpression or hyperactivation of TNK2 is linked to cancer progression, metastasis, and therapy resistance in malignancies like prostate, breast, and lung cancers. It promotes tumorigenesis by stabilizing oncogenic proteins (e.g., androgen receptor in prostate cancer) and suppressing tumor suppressors. These characteristics make TNK2 a potential therapeutic target, with inhibitors currently under preclinical investigation.
Recombinant TNK2 protein is engineered for in vitro studies to dissect its biochemical properties, substrate interactions, and inhibitor screening. Produced using expression systems like bacterial or mammalian cells, it retains enzymatic activity for kinase assays and structural studies. Researchers use it to map signaling networks, validate drug candidates, and explore TNK2’s role in disease models. Its application extends to elucidating mechanisms of kinase regulation and developing targeted therapies, highlighting its significance in both basic research and translational medicine.
