(H) Representative western blots showing HTT (ab-MAB5492) and HTT pS13 (ab-CHDI-90001039-1) from the detergent soluble fraction and HTT aggregates (ab-MAB5492) from the detergent insoluble fraction in TBK1 orthologue (ikke-1 or unc-51) RNAi-treated C. elegans lines expressing HTT N513 Q15 and HTT N513 Q128. (I) Quantification of the fold change in the ratio of pS13 HTT to total HTT compared to non-targeting RNAi from the experiments like in H (n=4).
