Casein Kinase II Inhibitor IV is primarily utilized in biochemical research to study the role of Casein Kinase II (CK2) in cellular processes. It is employed to inhibit CK2 activity, allowing researchers to investigate its involvement in signaling pathways, cell proliferation, and apoptosis. This inhibitor is particularly valuable in cancer research, as CK2 is often overexpressed in tumor cells and contributes to their survival. By blocking CK2, scientists can explore potential therapeutic strategies for cancer treatment. Additionally, it is used in studies related to neurodegenerative diseases, inflammation, and viral infections, where CK2 plays a regulatory role. Its application helps in understanding the molecular mechanisms underlying these conditions and in developing targeted therapies.
