Target Background

Function
Integral membrane protein associated with integrins, which regulates different processes, such as sperm-egg fusion, platelet activation and aggregation, and cell adhesion. 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. In myoblasts, associates with CD81 and PTGFRN and inhibits myotube fusion during muscle regeneration. In macrophages, associates with CD9 and beta-1 and beta-2 integrins, and prevents macrophage fusion into multinucleated giant cells specialized in ingesting complement-opsonized large particles. Also prevents the fusion between mononuclear cell progenitors into osteoclasts in charge of bone resorption. Acts as a receptor for PSG17. Involved in platelet activation and aggregation. Regulates paranodal junction formation. Involved in cell adhesion, cell motility and tumor metastasis. Also regulates integrin-dependent migration of macrophages, particularly relevant for inflammatory response in the lung.
Gene References into Functions
  1. The Cd9(-/-) and Cd9(-/-) Cd81(-/-) deletions are associated with a decreased microvilli density on the MII oocyte surface. Microvilli thickness is significantly increased whatever the deleted tetraspanin gene be. Only Cd9 deletion clearly disturbs the vesicular traffic, increasing the number of clathrin and exosome vesicles. PMID: 27879451
  2. CD9 regulates the T cell-stimulatory capacity of granulocyte-macrophage colony-stimulating factor (GM-CSF)-dependent bone marrow-derived Dendritic Cells (BMDCs), without affecting antigen presentation by fms-like tyrosine kinase 3 ligand (Flt3L)-dependent BMDCs. PMID: 28533221
  3. DPP4:CD9:TTSP as the protein complexes are necessary for early efficient MERS-coronavirus entry. PMID: 28759649
  4. Our results indicate that the suppression of cartilage degradation in CD9(-/-) could be in part related to an increase in the expression of the two main cartilage extracellular matrix proteins aggrecan and type II collagen. PMID: 27784871
  5. upregulation may play an important role in podocyte morphology, adhesion, and migration PMID: 25503725

  10. tetraspanin CD9 modulates molecular organization of integrins in lymphatic endothelial cells, thereby supporting several functions required for lymphangiogenesis PMID: 23223239
  11. Tetraspanin family member CD9 plays an important role in sperm-egg fusion. PMID: 22609062
