DESCRIPTION

Also known as CD40L_HUMAN, CD40LG, CD40L, TNFSF5, TRAP. Cytokine that acts as a ligand to CD40/TNFRSF5 (PubMed:1280226, PubMed:31331973). Costimulates T-cell proliferation and cytokine production (PubMed:8617933). 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 (PubMed:15067037, PubMed:31331973). Induces the activation of kinases MAPK8 and PAK2 in T-cells (PubMed:15067037). 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 (By similarity). Involved in immunoglobulin class switching (By similarity)., Acts as a ligand for integrins, specifically ITGA5:ITGB1 and ITGAV:ITGB3; both integrins and the CD40 receptor are required for activation of CD40-CD40LG signaling, which have cell-type dependent effects, such as B-cell activation, NF-kappa-B signaling and anti-apoptotic signaling. Homotrimer (PubMed:8626375, PubMed:11676606, PubMed:8589998). Interacts with isoform 3 of CD28 (PubMed:15067037). CD40 ligand, soluble form: Exists as either a monomer or a homotrimer (PubMed:8626375, PubMed:31331973). Forms a ternary complex between CD40 and integrins for CD40-CD40LG signaling (PubMed:31331973).
