CC -!- FUNCTION: Cytokine that acts as a ligand to CD40/TNFRSF5 (By
CC similarity). Costimulates T-cell proliferation and cytokine production
CC (By similarity). Its cross-linking on T-cells generates a costimulatory
CC signal which enhances the production of IL4 and IL10 in conjunction
CC with the TCR/CD3 ligation and CD28 costimulation (By similarity).
CC Induces the activation of NF-kappa-B (By similarity). Induces the
CC activation of kinases MAPK8 and PAK2 in T-cells (By similarity).
CC Mediates B-cell proliferation in the absence of co-stimulus as well as
CC IgE production in the presence of IL4 (By similarity). Involved in
CC immunoglobulin class switching (By similarity).
CC {ECO:0000250|UniProtKB:P27548, ECO:0000250|UniProtKB:P29965}.
CC -!- FUNCTION: [CD40 ligand, soluble form]: Acts as a ligand for integrins,
CC specifically ITGA5:ITGB1 and ITGAV:ITGB3; both integrins and the CD40
CC receptor are required for activation of CD40-CD40LG signaling, which
CC have cell-type dependent effects, such as B-cell activation, NF-kappa-B
CC signaling and anti-apoptotic signaling. {ECO:0000250|UniProtKB:P29965}.
CC -!- SUBUNIT: Homotrimer (By similarity). Interacts with CD28 (By
CC similarity). CD40 ligand, soluble form: Exists as either a monomer or a
CC homotrimer (By similarity). Forms a ternary complex between CD40 and
CC integrins for CD40-CD40LG signaling (By similarity).
CC {ECO:0000250|UniProtKB:P29965}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P29965};
CC Single-pass type II membrane protein {ECO:0000250|UniProtKB:P29965}.
CC Cell surface {ECO:0000250|UniProtKB:P29965}.
CC -!- SUBCELLULAR LOCATION: [CD40 ligand, soluble form]: Secreted
CC {ECO:0000250|UniProtKB:P29965}. Note=Release of soluble CD40L from
CC platelets is partially regulated by GP IIb/IIIa, actin polymerization,
CC and a matrix metalloproteinases (MMP) inhibitor-sensitive pathway.
CC {ECO:0000250|UniProtKB:P29965}.
CC -!- PTM: The soluble form derives from the membrane form by proteolytic
CC processing. {ECO:0000250|UniProtKB:P29965}.
CC -!- SIMILARITY: Belongs to the tumor necrosis factor family. {ECO:0000305}.
