**Background of DCTN4 Recombinant Protein**
DCTN4 (Dynactin 4), also known as p62. is a critical subunit of the dynactin complex, a multi-protein structure essential for intracellular transport processes. The dynactin complex works in concert with cytoplasmic dynein, a motor protein, to facilitate microtubule-based movement of cellular cargoes such as vesicles, organelles, and chromosomes. DCTN4 plays a stabilizing role in the dynactin assembly, bridging the Arp1 filament and other subunits like p150Glued. Its structural integrity is vital for maintaining the functional architecture of the complex, ensuring efficient dynein-mediated transport.
Recombinant DCTN4 protein is produced using expression systems (e.g., *E. coli*, mammalian cells*) to generate purified, biologically active forms for research. By cloning the DCTN4 gene into expression vectors, scientists can study its biochemical properties, interactions, and regulatory mechanisms in controlled settings. This approach enables detailed investigations into dynactin-dynein coordination, which is implicated in neuronal function, mitosis, and organelle positioning.
Dysregulation of DCTN4 has been linked to neurodegenerative diseases (e.g., amyotrophic lateral sclerosis) and cancer, where disrupted intracellular transport contributes to pathology. Recombinant DCTN4 serves as a tool for drug discovery, structural studies (e.g., cryo-EM), and functional assays to explore disease mechanisms or therapeutic targets. Its availability accelerates research into microtubule-dependent transport pathways, offering insights into cellular homeostasis and disease intervention strategies.
