2 Using a modified SDS-PAGE protocol (Phos-Tag) followed by Western blotting with specific anti-HUNTINGTIN antibodies, we efficiently resolved huntingtin fragments expressed in cellular contexts based on the presence of phosphorylated residues, we defined threonine 3 as the major site of huntingtin N17 phosphorylation and, finally, we identified IKK-beta as a kinase capable of phosphorylating threonine 3 in N-terminal hungtingtin fragments.
