Seth Margolis

Seth Margolis is an Associate Professor in the Department of Neuroscience at the Johns Hopkins University School of Medicine. He leads an active research laboratory focused on the role of the neuronal membrane proteasome (NMP) in synaptic regulation, neurodevelopment, and neurodegenerative diseases. His work integrates biochemical, proteomic, molecular, genetic, and behavioral approaches to understand protein homeostasis in the nervous system.

His research interests lie at the intersection of cellular and molecular neuroscience, with a focus on:

• Ubiquitin-proteasome pathways in neurons
• Activity-dependent protein degradation
• Neuronal membrane proteasome (NMP) signaling
• Synapse formation and plasticity
• Neurodevelopmental disorders (e.g., Angelman syndrome)
• Neurodegenerative diseases (e.g., Alzheimer’s disease)

Recent publications reveal a consistent trend in investigating the novel NMP complex, its extracellular signaling peptides, and their modulation of NMDAR-dependent signaling, synaptic function, and gene expression. His work spans from basic mechanisms of protein degradation to translational implications in pain, cognitive disorders, and neurodegeneration. Articles also highlight the role of UBE3A and Ephexin5 in disease pathways, demonstrating a deep mechanistic approach to understanding neurological conditions.

Seth Margolis actively mentors graduate students and postdoctoral researchers, with several former and current lab members contributing to high-impact publications. His lab has generated significant insights into proteasome-derived signaling, a relatively new field in neuroscience. While no specific grants are listed, his sustained publication record in top journals suggests active funding support.

He is affiliated with the Neuroscience Training Program at Johns Hopkins and contributes to the broader academic community through reviews and expert commentary. His laboratory continues to explore the composition, regulation, and physiological impact of the NMP complex, aiming to develop tools and frameworks for understanding neuronal signaling in health and disease.
