CD40 protein is a TNFSF5/CD40LG receptor that transduces signals through TRAF6 and MAP3K8-mediated pathways, activates ERK in macrophages and B cells, and induces immunoglobulin secretion. CD40 exists as monomers and homodimers and interacts with TRAF proteins (TRAF1, TRAF2, TRAF3, TRAF5, and TRAF6) . CD40 Protein, Human (HEK293, C-His) is the recombinant human-derived CD40 protein, expressed by HEK293 , with C-6*His labeled tag.
