CD40L, CD40LG, CD154, TNFSF5, TNFSF5IMD3, CD40LIGM, gp39, HIGM1, T-BAM, TRAP, IGM, IMD3, CD40 Ligand,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.
分子量
52.4 kDa, Due to glycosylation, the protein migrates to 55-60 kDa based on Tris-Bis PAGE result.
