      Biological Information
      ImmunogenHuman platelet glycoprotein
      ConcentrationPlease refer to the Certificate of Analysis for the lot-specific concentration.
      SpecificityThis antibody reacts with a 25 kDa molecular weight band on gels of non-reduced platelet membranes and immunoprecipitates a similar band from Iodine125-labeled platelets. The antigen is expressed on eosinophils, granulocytes, monocytes and numerous stromal cells. This CD9 antigen belongs to the TM4 superfamily of cell surface proteins with the N- and C-terminals localized in the cytoplasm.

      Entrez Gene Number
      Entrez Gene SummaryThe protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is a cell surface glycoprotein that is known to complex with integrins and other transmembrane 4 superfamily proteins. It can modulate cell adhesion and migration and also trigger platelet activation and aggregation. In addition, the protein appears to promote muscle cell fusion and support myotube maintenance.
