Dynamin-2 (DNM2) is a large GTPase protein encoded by the *DNM2* gene, playing a critical role in membrane remodeling processes such as clathrin-mediated endocytosis, intracellular vesicle trafficking, and organelle division. It belongs to the dynamin superfamily of mechanochemical enzymes, which hydrolyze GTP to generate mechanical force for membrane fission. Structurally, DNM2 contains a conserved N-terminal GTPase domain, a middle domain involved in oligomerization, a pleckstrin homology (PH) domain for phosphoinositide binding, and a C-terminal proline-rich domain (PRD) that interacts with SH3 domain-containing proteins. This modular architecture enables DNM2 to self-assemble into helical polymers at membrane necks, driving membrane constriction and scission.
Mutations in *DNM2* are linked to human diseases, including autosomal dominant Charcot-Marie-Tooth neuropathy (CMT), centronuclear myopathy (CNM), and hereditary diffuse leukoencephalopathy. These mutations often disrupt GTPase activity, membrane binding, or protein-protein interactions, leading to impaired endocytosis, cytoskeletal defects, or abnormal organelle morphology. Notably, DNM2 overexpression or hyperactivity is associated with cancer metastasis and chemoresistance, highlighting its diverse pathophysiological roles.
Recombinant DNM2 proteins are engineered for functional studies and therapeutic exploration. Produced via bacterial or mammalian expression systems, these proteins retain key biochemical properties, enabling in vitro analysis of GTPase activity, membrane interactions, and drug binding. Purification typically involves affinity chromatography and tag-based methods. Recombinant DNM2 is widely used to study disease mechanisms, screen small-molecule inhibitors (e.g., dynasore analogs), and develop gene therapies targeting DNM2-related disorders. Recent advances include cryo-EM structural studies of DNM2 oligomers and antisense oligonucleotide (ASO) strategies to modulate mutant DNM2 expression in neuromuscular diseases. Its dual role as a membrane fission regulator and disease driver makes DNM2 a compelling target for precision medicine.
