Recombinant human DUPD1 (Dual Specificity Phosphatase and Pseudophosphatase Domain-containing Protein 1) is a protein encoded by the *DUPD1* gene, belonging to the dual-specificity phosphatase (DSP) family. Unlike canonical DSPs, DUPD1 contains a pseudophosphatase domain, lacking critical catalytic residues, suggesting non-enzymatic regulatory roles. It is implicated in modulating cellular signaling pathways, particularly those involving MAPK (mitogen-activated protein kinase), though its exact physiological mechanisms remain unclear.
DUPD1 expression is observed in various tissues, with emerging links to immune regulation, cell differentiation, and apoptosis. Studies suggest its involvement in inflammatory responses and cancer progression, potentially acting as a tumor suppressor or oncogenic modulator depending on cellular context. Recombinant DUPD1 is typically produced via bacterial or mammalian expression systems, enabling functional studies such as protein-protein interaction assays, structural analysis, and pathway validation. Its production facilitates exploring molecular interactions, post-translational modifications, and therapeutic targeting. However, challenges persist in resolving its precise biological roles due to limited structural data and conflicting evidence in disease models. Current research focuses on elucidating DUPD1's role in cellular homeostasis and its potential as a biomarker or drug target in inflammation-related disorders and malignancies.
