Here we show that protein casein kinase 2 (CK2)-dependent phosphorylation controls the nuclear localization, aggregation and stability of ataxin-3 (ATXN3), the disease protein in spinocerebellar ataxia type 3 (SCA3). The main phosphorylation of ATXN3 in vivo thus occurred at serine residues within the three conserved UIMs. |

Mammalian E4B (UFD2a), a ubiquitin chain assembly factor (E4), copurified with the polyubiquitylation activity for ataxin-3. E4B interacted with, and thereby mediated polyubiquitylation of, ataxin-3. Collectively, these data suggest that E4B promotes the degradation of ataxin-3, and that this effect surmounts the stabilization of ataxin-3 conferred by expansion of the polyglutamine tract. |
