Sialophorin (SPN), also known as CD43. is a transmembrane glycoprotein predominantly expressed on the surface of immune cells, including T lymphocytes, neutrophils, and monocytes. It consists of a large extracellular domain rich in sialylated O-linked glycans, a transmembrane region, and a short cytoplasmic tail. SPN plays roles in cell adhesion, migration, and immune regulation by modulating interactions with extracellular ligands (e.g., ICAM-1) and intracellular signaling pathways. Its extensive glycosylation creates a repulsive barrier, influencing immune cell activation and pathogen recognition.
SPN antibodies are essential tools for studying its function and expression in health and disease. Dysregulation of SPN is linked to immunodeficiency, autoimmune disorders, and cancers like leukemia. Researchers use SPN-specific antibodies in flow cytometry, immunohistochemistry, and Western blotting to analyze protein localization, glycosylation patterns, and disease biomarkers. Monoclonal antibodies targeting distinct epitopes help elucidate SPN's structural and functional diversity. For example, certain antibodies detect glycosylation-dependent epitopes, revealing post-translational modifications critical for immune evasion in pathogens or tumors.
Overall, SPN antibodies serve as vital reagents in immunology research, offering insights into cellular communication, disease mechanisms, and potential therapeutic targets. Their applications span basic science to clinical diagnostics, emphasizing SPN's importance in immune homeostasis and pathology.
