DCTN2 (Dynactin Subunit 2), also known as p50 or dynamitin, is a critical component of the dynactin multiprotein complex, which regulates intracellular transport processes by linking cytoplasmic dynein motors to cargoes. As part of the dynactin complex, DCTN2 plays a pivotal role in maintaining the stability and functionality of the dynein-dynactin motor machinery, enabling retrograde vesicle trafficking, organelle positioning, and mitotic spindle organization. Structurally, it contains a conserved N-terminal domain that facilitates interactions with dynein intermediate chains and other dynactin subunits, such as DCTN1 (p150 glued).
Research highlights DCTN2's involvement in cellular division, neuronal transport, and maintenance of Golgi apparatus integrity. Dysregulation of DCTN2 has been implicated in neurodegenerative disorders (e.g., amyotrophic lateral sclerosis) and cancers due to impaired axonal transport or chromosomal segregation errors. Its role in modulating dynein activity also intersects with viral pathogenesis, as some pathogens exploit this transport system for intracellular replication.
Recombinant DCTN2 proteins are engineered using expression systems (e.g., E. coli, mammalian cells) to preserve post-translational modifications critical for function. These purified proteins serve as essential tools for in vitro studies, including protein interaction assays, structural analysis (e.g., cryo-EM), and drug discovery targeting transport-related diseases. Recent studies leverage recombinant DCTN2 to dissect mechanistic details of dynein regulation and develop therapeutic strategies for transportopathies. Its versatility in research underscores its importance in both basic cell biology and translational medicine.
