Function [CC]:Cytokine that binds to CD40/TNFRSF5 (PubMed:1280226). Costimulates T-cell proliferation and cytokine production. Its cross-linking on T-cells generates a costimulatory signal which enhances the production of IL4 and IL10 in conjunction with the TCR/CD3 ligation and CD28 costimulation (PubMed:8617933). Induces the activation of NF-kappa-B and kinases MAPK8 and PAK2 in T-cells. Induces tyrosine phosphorylation of isoform 3 of CD28 (PubMed:15067037). Mediates B-cell proliferation in the absence of co-stimulus as well as IgE production in the presence of IL4. Involved in immunoglobulin class switching (By similarity). {ECO:0000250|UniProtKB:P27548, ECO:0000269|PubMed:1280226, ECO:0000269|PubMed:15067037, ECO:0000269|PubMed:8617933}.; Release of soluble CD40L from platelets is partially regulated by GP IIb/IIIa, actin polymerization, and a matrix metalloproteinases (MMP) inhibitor-sensitive pathway. {ECO:0000269|PubMed:15193700}.
Site:SITE 112 113 Cleavage.
Tissue Specificity:Specifically expressed on activated CD4+ T-lymphocytes.
Disease:Immunodeficiency with hyper-IgM, type 1 (HIGM1) [MIM:308230]: 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. {ECO:0000269|PubMed:26545377, ECO:0000269|PubMed:7532185, ECO:0000269|PubMed:7678782, ECO:0000269|PubMed:7679206, ECO:0000269|PubMed:7679801, ECO:0000269|PubMed:7717401, ECO:0000269|PubMed:8094231, ECO:0000269|PubMed:8550833, ECO:0000269|PubMed:8889581, ECO:0000269|PubMed:9150729, ECO:0000269|PubMed:9746782}. Note=The disease is caused by mutations affecting the gene represented in this entry.
