**Background of Recombinant Human DEM1 Protein**
DEM1 (Dual-specificity EMT-associated protein 1) is a conserved eukaryotic protein implicated in regulating cytoskeletal dynamics, cell division, and epithelial-mesenchymal transition (EMT). Naturally expressed in humans, DEM1 interacts with microtubules and actin filaments, playing roles in mitotic spindle organization, chromosome segregation, and cell migration. Its dysfunction has been associated with developmental disorders and cancer metastasis due to altered cell adhesion and motility.
Recombinant human DEM1 protein is engineered via heterologous expression systems (e.g., *E. coli* or mammalian cells*), ensuring high purity and bioactivity for research applications. It typically retains functional domains, including microtubule-binding regions and phosphorylation sites critical for signaling. Recombinant production enables studies on DEM1’s molecular interactions, structural properties, and regulatory mechanisms in cellular processes. Researchers utilize it to explore pathways in embryogenesis, tumor progression, and tissue repair. Further, it serves as a tool for drug screening targeting EMT-related diseases or mitotic errors. Standardized recombinant DEM1 facilitates reproducibility in biochemical assays, antibody development, and structural studies, bridging gaps in understanding its dual roles in normal physiology and pathology.
