Msi-1 binds to the 3′-untranslated region (UTR) of its target mRNAs in neural stem/progenitor cells (NS/PCs), repressing their translation, and interfering with NS/PC differentiation thus maintaining NP/PCs in the undifferentiated state. It is associated with maintenance and asymmetric cell division of neural stem cells. Loss of Msi-1 function disrupts the balance between germ-line stem cell renewal and differentiation, causing premature differentiation. Msi-1 has been shown to regulate the Notch and Wnt signaling pathway. Upregulation of Msi-1 augments Notch signaling, via translational repression of the Notch signaling antagonist m-Numb, thereby inhibiting the differentiation of neural stem cells into neurons. Expression of Msi1- has been detected in several human cancers including brain tumors, suggesting its role in oncogenic development.
