Neuronal and glial deposition of misfolded, proteolytically processed, polyubiquitinated and abnormally phosphorylated C-terminal fragments (CTFs) of the TAR DNA binding protein-43 (TDP-43) is a pathological hallmark of frontotemporal lobar degeneration with ubiquitin positive inclusions (FTLD-U) and certain cases of amyotrophic lateral sclerosis. We demonstrate that TDP-43 can be proteolytically processed ... More
