Nsf Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
NSF (N-Ethylmaleimide-Sensitive Fusion Protein) is a hexameric ATPase that plays a critical role in intracellular membrane fusion events throughout the cell. Originally discovered for its role in NSF-mediated fusion reactions, this protein is essential for synaptic vesicle recycling, Golgi maintenance, and endosomal trafficking. NSF functions as a molecular chaperone that disassembles SNARE complexes after membrane fusion, allowing SNARE proteins to be recycled for subsequent rounds of fusion[1][2].
