CD27 molecule(CD27) Homo sapiens The protein encoded byThis 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-kappaB and MAPK8/JNK. Adaptor proteins TRAF2 and TRAF5 have been shown to mediate the signaling process ofThis receptor. CD27-binding protein (SIVA), a proapoptotic protein, can bind toThis receptor and is thought to play an important role in the apoptosis induced byThis receptor. [provided by RefSeq, Jul 2008]
