**Background of PTPRU Recombinant Protein**
PTPRU (Protein Tyrosine Phosphatase Receptor Type U) is a member of the protein tyrosine phosphatase (PTP) family, which plays a critical role in regulating cellular signaling by dephosphorylating tyrosine residues on target proteins. This enzyme is integral to maintaining the balance of tyrosine phosphorylation, a key mechanism controlling cell adhesion, migration, proliferation, and differentiation. PTPRU, also known as PTPρ or PTP-LAR, is a transmembrane receptor-type phosphatase characterized by an extracellular fibronectin-type III domain, a single transmembrane region, and a cytoplasmic catalytic domain. Its structure suggests involvement in cell-cell and cell-matrix interactions, particularly in epithelial and endothelial tissues.
Dysregulation of PTPRU has been implicated in various pathologies, including cancer and developmental disorders. For instance, reduced PTPRU expression is linked to increased cell invasiveness in colorectal cancer, while aberrant signaling contributes to tumor progression and metastasis in other malignancies. Additionally, PTPRU interacts with signaling pathways such as Wnt/β-catenin and Hippo, highlighting its role in tissue homeostasis and disease.
Recombinant PTPRU protein is engineered using expression systems (e.g., bacterial, mammalian) to produce purified, functional enzyme for research and therapeutic applications. It enables detailed study of PTPRU’s enzymatic activity, substrate specificity, and regulatory mechanisms. Researchers utilize it to investigate its role in disease models, screen inhibitors for drug development, or restore normal phosphatase activity in pathological conditions. Challenges in producing active recombinant PTPRU include preserving its native conformation and catalytic efficiency, often addressed through optimized expression and purification strategies.
Overall, PTPRU recombinant protein serves as a vital tool for unraveling its biological functions and therapeutic potential in tyrosine phosphorylation-related diseases.
