  • Function
    Mediates B-cell proliferation in the absence of co-stimulus as well as IgE production in the presence of IL-4. Involved in immunoglobulin class switching.
    Release of soluble CD40L from platelets is partially regulated by GP IIb/IIIa, actin polymerization, and an matrix metalloproteinases (MMP) inhibitor-sensitive pathway.
  • Tissue specificity
    Specifically expressed on activated CD4+ T-lymphocytes.
  • Involvement in disease
    Defects in CD40LG are the cause of X-linked immunodeficiency with hyper-IgM type 1 (HIGM1) [MIM:308230]; also known as X-linked hyper IgM syndrome (XHIM). HIGM1 is an immunoglobulin isotype switch defect characterized by elevated concentrations of serum IgM and decreased amounts of all other isotypes. Affected males present at an early age (usually within the first year of life) recurrent bacterial and opportunistic infections, including Pneumocystis carinii pneumonia and intractable diarrhea due to cryptosporidium infection. Despite substitution treatment with intravenous immunoglobulin, the overall prognosis is rather poor, with a death rate of about 10% before adolescence.
  • Sequence similarities
    Belongs to the tumor necrosis factor family.
  • Post-translational
    modifications
    The soluble form derives from the membrane form by proteolytic processing.
    N-linked glycan is a mixture of high mannose and complex type. Glycan structure does not influence binding affinity to CD40.
    Not O-glycosylated.
  • Cellular localization
    Secreted and Cell membrane.
  • Information by UniProt
