(C) Representative immunofluorescence images of eGFP HTTex1 72Q or its phosphorylation-deficient variant S13A/S16A upon coexpression with TBK1 KD or TBK1 or TBK1 Δ690-713 (ab-anti-Myc) with for 48 hour in HEK293 cells (scale bar 20μm). (D) The graph indicates the percentage of co-transfected cells presenting aggregates upon expression of the indicated kinase, from the experiments like in C (n=3).
