Numb is an evolutionary conserved protein that plays critical roles in cell fate determination. Mammalian Numb displays a higher degree of structural complexity compared to the Drosophila homolog based on the number of encoding genes (Numb and Numb-like) and of alternative spliced isoforms. Accordingly, Numb proteins display a complex pattern of functions such as the control of asymmetric cell division and cell fate choice, endocytosis, cell adhesion, cell migration, ubiquitination of specific substrates and a number of signaling pathways (i.e. Notch, Hedgehog, p53). Recent findings indicate that, besides controlling such physiologic developmental processes, subversion of the above Numb-dependent events plays a critical role in disease (e.g. cancer). We will review here the multiple functions of mNumb and their underlying molecular mechanisms in development and disease.
