CD40L/CD154/TRAP, Human (HEK293, hFc-Flag)

CD40L (CD154; TRAP) is a ligand to CD40/TNFRSF5, acts function by generating a costimulatory signal that up-regulates IL-4 synthesis[1]. CD40L is specifically expressed on activated CD4+ T-lymphocytes and involves in activation of NF-κB/MAPK pathway[2][3]. CD40L also involves in B cell differentiation, maturation, and apoptosis[4]. CD40L in human, cleaved into 2 chains of membrane form (1-261 a.a.) and soluble form (113-261 a.a.) which serves as a ligand for integrins (ITGA5:ITGB1 and ITGAV:ITGB3) . CD40L/CD154/TRAP Protein, Human (HEK293, hFc-Flag) has a total length of 248 amino acids (M13-L261), is expressed in HEK392 cells with N-terminal hFc- and Flag-tag.
