M337V human TDP-43 cDNA was cloned into pCMV6-AC-GFP (Origene) to generate a mutant TDP-43 construct C-terminally tagged with tGFP18 (link). HA-NFAT1(1-460)-GFP was a gift from Anjana Rao (Addgene plasmid #11107). Huntingtin protein-encoding constructs, pT-Rex-Htt46Q-Tc1-mCherry and pT-Rex-Htt25Q-Tc1-mCherry, were gifts from Dr. Danny Hatters (University of Melbourne, Australia)19 (link). pEGFP-SOD1, pEGFP-SOD1-A4V, pEGFP-SOD1-G93A were gifts from Dr. Brad Turner (The Florey Institute of Neuroscience and Mental Health, Australia)20 (link). SOD1-tdTomato constructs were created by replacing the GFP sequences in the SOD1-GFP plasmids with tdTomato (Genscript)18 (link). The expression vector pCMV6-AC-GFP containing FUS was obtained from Origene and site directed mutagenesis was performed by Genscript to create the R495X mutant18 (link). Plasmids containing sequences encoding wild type (WT) and temperature-sensitive double mutant (R188Q, R261Q; DM) firefly luciferase-eGFP were a gift from Prof Ulrich Hartl (Max Plank Institute, Germany)21 and were recloned into pcDNA4/TO (Life Technologies) for mammalian cell transfection.
