HUNK (Hormonally Up-Regulated Neu-Associated Kinase): HUNK is a gene that encodes a protein kinase regulated by hormonal signals. It has been linked to breast cancer, where overexpression may promote tumor growth and metastasis. By participating in intracellular signaling pathways influenced by hormones such as estrogen, HUNK plays a significant role in cancer biology and is being explored as a potential therapeutic target.
