CD40L/CD154/TRAP, Human

• Description:

  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 has a total length of 149 amino acids (M113-L261), is expressed in E. coli cells with tag free.
