target relevance
CD40 ligand or CD40L, also called CD154,  is a protein that is primarily expressed on activated T cells and is a member of the TNF superfamily of molecules. It binds to CD40 (protein) on antigen-presenting cells (APC), which leads to many effects depending on the target cell type. In total CD40L has three binding partners: CD40, α5β1 integrin and αIIbβ3. CD154 acts as a costimulatory molecule and is particularly important on a subset of T cells called T follicular helper cells.

Function
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). {ECO:0000250|UniProtKB:P27548, ECO:0000269|PubMed:1280226, ECO:0000269|PubMed:15067037, ECO:0000269|PubMed:31331973, ECO:0000269|PubMed:8617933}.; FUNCTION: [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. {ECO:0000269|PubMed:31331973}.
Subellular location
SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:8626375}; Single-pass type II membrane protein {ECO:0000303|PubMed:8626375}. Cell surface {ECO:0000269|PubMed:15067037, ECO:0000269|PubMed:7678552}.; SUBCELLULAR LOCATION: [CD40 ligand, soluble form]: Secreted {ECO:0000269|PubMed:8626375}. Note=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}.
Tissues
TISSUE SPECIFICITY: Specifically expressed on activated CD4+ T-lymphocytes.
Structure
SUBUNIT: Homotrimer (PubMed:11676606, PubMed:8589998, PubMed:8626375). Interacts with isoform 3 of CD28 (PubMed:15067037). CD40 ligand, soluble form: Exists as either a monomer or a homotrimer (PubMed:31331973, PubMed:8626375). Forms a ternary complex between CD40 and integrins for CD40-CD40LG signaling (PubMed:31331973). {ECO:0000269|PubMed:11676606, ECO:0000269|PubMed:15067037, ECO:0000269|PubMed:31331973, ECO:0000269|PubMed:8589998, ECO:0000269|PubMed:8626375}.
Post-translational modification
PTM: The soluble form derives from the membrane form by proteolytic processing. {ECO:0000269|PubMed:8626375}.; PTM: N-linked glycan is a mixture of high mannose and complex type. Glycan structure does not influence binding affinity to CD40. {ECO:0000269|PubMed:11676606}.; PTM: Not O-glycosylated.
