General description
In mammals, the Musashi family is important for cell fate determination, playing roles in maintenance of the stem-cell state, cellular differentiation, nuclear signaling and tumorigenesis. Musashi-1 (also known as Msi1), is selectivley expressed in neural progenitor cells, including neural stem cells. Outside the nervous system, Musashi-1 is a selective marker for intestinal stem or early lineage cells. Musashi-1 interacts with the Notch pathway during asymmetric cell division by binding the 3′ UTR of Numb. Numb is prevented from repressing Notch signaling when Musashi-1 is present.
