These proteins include the microtubule-associated protein tau, the transactive response DNA binding protein molecular weight 43 (TDP-43), fused in sarcoma (FUS), Ewing’s sarcoma (EWS) or TATA-binding protein-associated factor 15 (TAF15) (Rademakers et al., 2012; Mackenzie and Neumann, 2016). Here, FUS is linked to sarcoma.
