NMR Spectroscopy

About / Overview

The mission of the NJ-ACS NMR TG is to bring together scientists who use nuclear magnetic resonance (NMR) as a research tool from academia and industry, students of NMR, as well as vendors of NMR-related products. It organizes monthly meetings that consist of a social hour, a buffet dinner, followed by a presentation by an invited speaker.

From time to time, the NMR Topical Group hosts scientific symposia on topics related to nuclear magnetic resonance (NMR). These events serve as excellent venues for networking within the local scientific community. Also, through its activities, the NMR Topical Group raises public awareness of the American Chemical Society (ACS) and its service to the scientific community.

The NMR Spectroscopy Topical Group operates under the auspices of the North Jersey Section of the American Chemical Society (NJ-ACS), which is a non-profit organization that qualifies for tax exempt status under section 501(c)(3) of the Internal Revenue Service code.

NMR Seminar: Structural Determination of Neurodegenerative Disease-Associated Proteins Inside Cells

February 22, 2024 | 12pm - 1pm

 Abstract

The misfolded proteins associated with neurodegenerative disease can adopt a variety of different conformations, some of which are toxic. Because these proteins have identical amino acid sequences, the cellular environment clearly influences the final state, yet most structural studies do not include the cellular context and, perhaps because we are not studying the correct conformation, not a single therapeutic strategy for these diseases addresses the underlying protein misfolding pathology. Using new sensitivity-enhancement technology for solid state NMR spectroscopy, Dynamic Nuclear Polarization, we study protein structure in native environments -inside living cells -to reveal how both healthy and disease-relevant cellular environments influence protein structure. Because NMR reports quantitatively, with atomic level precision, on all sampled conformation, it can not only report on structural polymorphs but also provide experimental restraints on regions of intrinsic disorder, complementing insights from cryo-electron microscopy and tomography.Using this approach, we recently demonstrated that an amyloid fibril with a solved cryo-EM structure was polymorphic and found that when those fibrils were used to seed amyloid propagation in mammalian cells, the minority polymorph in the purified setting became the majority polymorph inside cells. With this approach we can understand the mechanism of protein-based inheritance of amyloid aggregates and correlate phenotype withconformational ensembles.
