**Background of DNM3 Recombinant Protein**
Dynamin-3 (DNM3), a member of the dynamin family of large GTPases, plays a critical role in membrane remodeling and intracellular trafficking. This protein is structurally characterized by a GTPase domain, a middle domain, a pleckstrin homology (PH) domain, and a proline-rich domain (PRD). DNM3 is involved in clathrin-mediated endocytosis, vesicle scission, and cytoskeletal regulation, though its functions are less well-characterized compared to dynamin-1 (neuronal-specific) and dynamin-2 (ubiquitously expressed). DNM3 is broadly expressed in tissues, including the brain, testis, and lungs, suggesting diverse cellular roles beyond neurotransmission.
Recombinant DNM3 protein is engineered using expression systems (e.g., *E. coli*, mammalian, or insect cells*) to produce purified, functional protein for *in vitro* studies. Its recombinant form enables researchers to investigate enzymatic activity, structure-function relationships, and interactions with binding partners like SH3 domain-containing proteins or membrane lipids. DNM3's GTPase activity, stimulated by lipid membranes or microtubules, is a key focus, as dysregulation may contribute to neurological disorders, cancer, or tissue-specific pathologies.
Studies using recombinant DNM3 have advanced understanding of its role in cellular processes, such as endocytic vesicle formation and actin dynamics. Mutational analyses reveal how specific domains mediate membrane binding or oligomerization, while structural studies (e.g., cryo-EM) provide insights into conformational changes during GTP hydrolysis. Additionally, DNM3's interaction with disease-associated proteins highlights its potential as a therapeutic target. Despite progress, functional redundancy among dynamin isoforms and context-dependent roles remain areas of active research, underscoring the need for tailored recombinant tools to dissect DNM3-specific mechanisms in health and disease.
