**Background of TSPAN9 Recombinant Protein**
TSPAN9. a member of the tetraspanin superfamily, is a transmembrane protein characterized by four conserved transmembrane domains and distinct extracellular loops. Tetraspanins play critical roles in organizing membrane microdomains, mediating cell-cell interactions, and regulating intracellular signaling. TSPAN9 is broadly expressed in various tissues, including the brain, immune system, and epithelial cells, and has been implicated in diverse biological processes such as cell adhesion, migration, and cancer progression.
The recombinant TSPAN9 protein is engineered through molecular cloning and expression systems (e.g., mammalian, insect, or bacterial cells) to produce a purified, functional form of the protein. This recombinant version typically retains key structural features, such as the large extracellular loop (LEL), which is critical for interactions with ligands, receptors, or other tetraspanins. Researchers utilize TSPAN9 recombinant proteins to study its molecular interactions, signaling pathways, and role in diseases.
Emerging evidence highlights TSPAN9's involvement in cancer biology, where it may act as a tumor suppressor or promoter depending on context. For instance, it modulates Wnt/β-catenin signaling and influences metastasis in colorectal and gastric cancers. Additionally, TSPAN9 is linked to neurological disorders and immune regulation, suggesting therapeutic potential. Its recombinant form is essential for developing antibodies, diagnostic assays, and functional studies, providing a tool to explore its mechanistic contributions to health and disease.
Overall, TSPAN9 recombinant protein serves as a vital resource for dissecting the multifaceted roles of tetraspanins in cellular communication and pathology.
