Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 26 kDa.

For unpurified use at 1/500 - 1/1000.

  • Application notes
    Is unsuitable for Flow Cyt,ICC/IF,IHC-P or IP.
  • Target

    • Function
      May play an important role in the regulation of lymphoma cell growth. Interacts with a 16-kDa Leu-13 protein to form a complex possibly involved in signal transduction. May acts a the viral receptor for HCV.
    • Tissue specificity
      Hematolymphoid, neuroectodermal and mesenchymal tumor cell lines.
    • Involvement in disease
      Defects in CD81 are the cause of immunodeficiency common variable type 6 (CVID6) [MIM:613496]; also called antibody deficiency due to CD81 defect. CVID6 is a primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B cells is usually in the normal range, but can be low.
    • Sequence similarities
      Belongs to the tetraspanin (TM4SF) family.
    • Post-translational
      modifications
      Not glycosylated.
    • Cellular localization
      Membrane.
