Anti-CD9 (PE), clone HI9a

Protein function: Integral membrane protein associated with integrins, which regulates different processes, such as sperm-egg fusion, platelet activation and aggregation, and cell adhesion (PubMed:8478605, PubMed:14575715, PubMed:18541721). Present at the cell surface of oocytes and plays a key role in sperm-egg fusion, possibly by organizing multiprotein complexes and the morphology of the membrane required for the fusion. Acts as a receptor for PSG17. Involved in platelet activation and aggregation (PubMed:18541721). Regulates paranodal junction formation. Involved in cell adhesion, cell motility and tumor metastasis (PubMed:8478605, PubMed:7511626). [The UniProt Consortium]
