Previous GeneCards Identifiers for SPN Gene
The protein encoded by this gene is a major sialoglycoprotein found on the surface of thymocytes, T lymphocytes, monocytes, granulocytes, and some B lymphocytes. It may be part of a physiologic ligand-receptor complex involved in T-cell activation. During T-cell activation, this protein is actively removed from the T-cell-APC (antigen-presenting cell) contact site, suggesting a negative regulatory role in adaptive immune response.

GeneCards Summary for SPN Gene
SPN (Sialophorin) is a Protein Coding gene. Diseases associated with SPN include mental retardation, autosomal dominant 24 and wiskott-aldrich syndrome. Among its related pathways are Platelet activation, signaling and aggregation and Dendritic Cells Developmental Lineage Pathway. GO annotations related to this gene include transmembrane signaling receptor activity.
UniProtKB/Swiss-Prot for SPN Gene
One of the major glycoproteins of thymocytes and T lymphocytes. Plays a role in the physicochemical properties of the T-cell surface and in lectin binding. Presents carbohydrate ligands to selectins. Has an extended rodlike structure that could protrude above the glycocalyx of the cell and allow multiple glycan chains to be accessible for binding. Is a counter-receptor for SN/Siglec-1 (By similarity). During T-cell activation is actively removed from the T-cell-APC (antigen-presenting cell) contact site thus suggesting a negative regulatory role in adaptive immune response (By similarity).
