General info

Function

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).. CD40 ligand, soluble form. 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.

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.
