CD40 Protein, Human (Biotinylated, HEK293, His-Avi)

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 (Biotinylated, HEK293, His-Avi) is the recombinant human-derived CD40 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of CD40 Protein, Human (Biotinylated, HEK293, His-Avi) is 173 a.a., with molecular weight of 35-40 kDa.

CD40 Protein, acting as the receptor for TNFSF5/CD40LG, is instrumental in transducing signals through TRAF6- and MAP3K8-mediated pathways, leading to the activation of ERK in macrophages and B cells and subsequent induction of immunoglobulin secretion. Existing in both monomeric and homodimeric forms, CD40 Protein exhibits variations in its homodimeric structure, as observed in the bladder carcinoma cell line Hu549. The receptor interacts with key signaling molecules such as TRAF1, TRAF2, TRAF3, TRAF5, and TRAF6, with the crucial interaction occurring between CD40 Protein, TRAF6, and MAP3K8, thereby playing a pivotal role in ERK activation.
