Neuroprotective Role of E3 Ubiquitin Ligase TRIM2 in Parkinson's Disease: Attenuation of Oxidative Stress and Apoptosis via Promoting ELAVL1 Ubiquitination

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
The E3 ubiquitin ligase TRIM2 confers neuroprotection against 6‐OHDA‐induced oxidative stress and apoptosis. It exerts this function by binding to ELAVL1 and promoting its degradation via the ubiquitin‐proteasome pathway. Thus, our study reveals the TRIM2‐ELAVL1 axis as a key regulatory mechanism for neuronal survival under 6‐OHDA‐stimulated toxic ...
