MYC and amyotrophic lateral sclerosis: The MS analysis of biotinylated proteins from Neuro-2a cells transfected with myc-BirA∗-tagged human TDP-43 (myc-BirA∗-TDP-43) or TDP-C-terminal fragment (myc-BirA∗-TDP-CTF), which is a major component of insoluble cytoplasmic aggregates in ALS/FTD, identified 254 proteins and 389 proteins in the interactomes of TDP-43 and TDP-CTF, respectively.
