CD40 [ENSP00000361359]
CD40 molecule, TNF receptor superfamily member 5; Receptor for TNFSF5/CD40LG
TRAF5 [ENSP00000261464]
TNF receptor-associated factor 5; Adapter protein and signal transducer that links members of the tumor necrosis factor receptor family to different signaling pathways by association with the receptor cytoplasmic domain and kinases. Mediates activation of NF-kappa-B and probably JNK. Seems to be involved in apoptosis
