MI-2 is primarily utilized in research settings to study its interaction with the NOTCH signaling pathway, which plays a crucial role in cellular differentiation, proliferation, and apoptosis. It is particularly investigated for its potential to inhibit the activity of the MAML1 protein, a key coactivator in the NOTCH pathway. This inhibition is of significant interest in cancer research, as aberrant NOTCH signaling is implicated in various malignancies. By targeting this pathway, MI-2 serves as a tool to explore therapeutic strategies for cancers where NOTCH signaling is dysregulated, such as T-cell acute lymphoblastic leukemia (T-ALL) and other NOTCH-dependent tumors. Additionally, it aids in understanding the broader biological mechanisms influenced by NOTCH signaling in both normal and pathological conditions.
