Axonal transport of TDP-43 mRNA granules is impaired by ALS-causing mutations

TDP-43 in ALS: stay on target…almost there

ALS is associated with RNA processing impairments involving the RNA-binding protein TDP-43. Pioneering a novel RNA beacon to illuminate RNA trafficking in neurons, Alami et al. (2014) discover a cytoplasmic function for TDP-43, suggesting a new disease mechanism.
