We focused on the ALS/FTD‐associated RNA‐binding protein TDP‐43 because hnRNPA2 and TDP‐43 are thought to physically interact to mediate RNA processing (Buratti et al, 2005; D'Ambrogio et al, 2009) and they co‐aggregate in patients (Kim et al, 2013) and in vitro (Ryan et al, 2018). Here, HNRNPA2B1 is linked to amyotrophic lateral sclerosis.
