The mechanisms involved in the differential regulation of these highly homologous proteins are unknown. We present evidence that Pax3, but not Pax7, is regulated by ubiquitination and proteasomal degradation during adult muscle stem cell activation. Intriguingly, only monoubiquitinated forms of Pax3 could be detected. Mutation of two specific lysine residues in the C-terminal region of Pax3 reduced the extent of its monoubiquitination and susceptibility to proteasomal degradation, whereas introduction of a key lysine into the C-terminal region of Pax7 rendered that protein susceptible to monoubiquitination and proteasomal degradation. Monoubiquitinated Pax3 was shuttled to the intrinsic proteasomal protein S5a by interacting specifically with the ubiquitin-binding protein Rad23B. Functionally, sustained expression of Pax3 proteins inhibited myogenic differentiation, demonstrating that Pax3 degradation is an essential step for the progression of the myogenic program. These results reveal an important mechanism of Pax3 regulation in muscle progenitors and an unrecognized role of protein monoubiquitination in mediating proteasomal degradation."xsd:string |
