Alternate Names:  TNFSF5, TRAP, CD154, gp39, T-BAM               Accession Number: P29965
Description:  CD40-Ligand, or CD154, is a membrane glycoprotein and differentiation antigen that is expressed on the surface of T cells, monocytes, basophils, eosinophils, platelets, dendritic cells, and endothelial cells. CD40-Ligand binds and activates the CD40 receptor on antigen-presenting cells. CD40-Ligand stimulates B cell proliferation, immunoglobulin class switching, and antibody secretion. CD40-Ligand also induces cytokine production and tumoricidal activity in peripheral blood monocytes. CD40-Ligand is a co-stimulator of activated T cell proliferation and inflammatory protein production.
Source:  Genetically modified E.coli.
Predicted MW: Monomer, 16.3 kDa (149 aa)
Formulation:  Lyophilized from a sterile (0.2 micron) filtered aqueous solution containing 10 mM sodium phosphate, pH 7.5
