High-resolution NMR spectroscopy of proteins in intact mitochondria.

High-resolution NMR spectroscopy reveals detailed protein interactions within intact mitochondria, including alpha-synuclein membrane binding and post-translational regulation.

• Why it matters: Understanding mitochondrial protein behavior is crucial for deciphering cellular energy processes and disease mechanisms, yet studying proteins in their native mitochondrial environment remains challenging.
• What they did: The authors developed a method to deliver proteins into isolated mitochondria via electroporation and used NMR to analyze protein stability, dimerization, and membrane interactions at atomic resolution.
• The result: This approach enables precise investigation of mitochondrial protein functions and interactions, advancing insights into mitochondrial health, stress responses, and related diseases.
