IRE1 regulates the proteostasis of TDP-43/TARDBP in ALS/FTD through ribosome-associated quality control
This work demonstrates that inositol-requiring enzyme 1 (IRE1) interacts with NEMF, a core component of the ribosome-associated quality control (RQC) machinery, to regulate the proteostasis of TDP-43, a key protein implicated in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Researchers show that IRE1 links the unfolded protein response to RQC, providing a mechanistic connection between ER stress pathways and TDP-43 aggregation. For your work in cellular and tissular disruptions, this discovery highlights a novel regulatory axis that could be targeted to mitigate proteotoxicity in neurodegenerative diseases, with broader implications for understanding protein quality control mechanisms in aging and reproductive tissue homeostasis.
