TARDBP and amyotrophic lateral sclerosis: C‐terminal fragments were not demonstrated in tissue from the Y374X TDP‐43 patient or a p.I113T‐SOD1 ALS patient using an antibody directed against phosphorylated serin at 409/410 located at the C‐terminal end of TDP‐43 (Figure 4C) or an antibody directed against the C‐terminal (Figure 4D) or the N‐terminal (Figure 4E) end of TDP‐43.
