Armenian Hamster anti CD27

Members of the tumor necrosis factor receptor (TNFR) family are emerging as important molecules impliCated in the regulation of prolifeRation, differentiation and survival of T and B lymphocytes. Among these receptors is CD27, the function of which has thus far only been studied in the Human system, where it amplifies the T cell prolifeRative response induced by TCR triggering. The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is required for geneRation and long-term maintenance of T cell immunity. It binds to ligand CD70, and plays a key role in regulating B-cell activation and immunoglobulin synthesis. This receptor transduces signals that lead to the activation of NF-?B and MAPK8/JNK. Adaptor proteins TRAF2 and TRAF5 have been shown to mediate the signaling process of this receptor. CD27-binding protein (SIVA), a pro-apoptotic protein, can bind to this receptor and is thought to play an important role in the apoptosis induced by this receptor.
