GABARAP and Parkinsonism: Overall, we discuss the emerging molecular crosstalk between σ1R and GABARAP, its potential impact on neuronal homeostasis, and how σ1R’s pharmacological modulation might be leveraged to bias GABARAP function toward autophagy in diseases such as amyotrophic lateral sclerosis, Huntington’s, Parkinson’s, and Alzheimer’s disease.
