Getting stress out of stressed‐out stress granules [PDF]

open access: yesThe EMBO Journal, 2017
Amyotrophic lateral sclerosis (ALS) pathology is linked to the aberrant aggregation of specific proteins, including TDP‐43, FUS, and SOD1, but it is not clear why these aggregation events cause ALS. In this issue of The EMBO Journal , Mateju et al (2017) report a direct link between misfolded proteins accumulating in stress granules and the phase ...
