Dnm2 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
DNM2 (Dynamin 2) encodes a GTPase critical for membrane fission events, particularly in endocytosis and mitochondrial dynamics. Mutations in DNM2 cause dominant intermediate Charcot-Marie-Tooth disease (CMT) type B, and dynamin dysfunction is implicated in various neurodegenerative conditions. [1]
Dynamin 2 is a member of the dynamin family of large GTPases that mediate membrane remodeling and fission. It plays essential roles in clathrin-mediated endocytosis, synaptic vesicle recycling, mitochondrial fission, and cytoskeletal regulation. The protein assembles into spirals around necked membranes and uses GTP hydrolysis to drive membrane scission. [2]

DNM2 is expressed throughout the nervous system:
The study of Dnm2 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
