**Background of Recombinant Human SUSD3 Protein**
The recombinant human SUSD3 (Sushi domain-containing protein 3) protein is a genetically engineered version of the naturally occurring SUSD3 protein, belonging to the SUSD protein family known for their sushi-like protein domains. SUSD3 is a type I transmembrane glycoprotein involved in diverse biological processes, including cell adhesion, immune regulation, and cellular signaling. It contains characteristic sushi domains (complement control protein modules) in its extracellular region, which mediate protein-protein and protein-ligand interactions, potentially influencing immune cell communication and tumor microenvironment modulation.
SUSD3 has garnered interest due to its suggested roles in cancer progression and immune evasion. Studies indicate its overexpression in certain cancers, where it may promote metastasis or suppress anti-tumor immune responses. Recombinant SUSD3 is typically produced in mammalian expression systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications, enabling functional and structural studies. Researchers utilize this protein to investigate its interactions with receptors like TIGIT or CD155. explore its impact on immune checkpoints, and develop therapeutic strategies targeting SUSD3-associated pathways. Despite its emerging significance, the exact molecular mechanisms and broader physiological roles of SUSD3 remain under investigation, necessitating further research to unlock its diagnostic or therapeutic potential.
