[Research News] Study Reveals Novel Therapeutic Target to Eliminate Unwanted and Misfolded Proteins
Atsushi Hatanaka, a graduate student, and Akira Kobayashi, a professor, both from the Laboratory for Genetic Code, Graduate School of Life and Medical Sciences, and their research team discovered the hidden mechanism of "aggrephagy," with major implications for degenerative protein diseases.
In cells, the ubiquitin‒proteasome system (UPS) plays a key role in the elimination of unwanted or misfolded proteins. When UPS fails, cells activate a backup process called "aggrephagy" for clearing ubiquitin-tagged proteins. However, the associated mechanism behind this process remains unknown. Recently, Hatanaka, Kobayashi, and their colleagues have demonstrated how another protein called NRF1 facilitates aggrephagy, thereby providing new therapeutic targets for diseases resulting from misfolded proteins.
These findings pave the way toward developing novel therapeutics for degenerative diseases such as Alzheimer's disease, Parkinson's disease, and dementia with Lewy bodies.

The transcription factor NRF1 (NFE2L1) activates aggrephagy by inducing p62 and GABARAPL1 after proteasome inhibition to maintain proteostasis (2023) Scientific Reports, 13 (1), art. no. 14405
