KRN2 is primarily utilized in the field of pharmaceutical research and development, particularly in the study of kinase inhibitors. It serves as a valuable tool in understanding cellular signaling pathways and their role in various diseases, including cancer. Researchers use KRN2 to investigate the inhibition of specific kinases, which are enzymes that play a critical role in regulating cell functions. By targeting these kinases, KRN2 helps in identifying potential therapeutic strategies for treating conditions characterized by abnormal cell proliferation or signaling. Additionally, it aids in the development of more effective and targeted drugs, contributing to advancements in personalized medicine and oncology treatments.
