Technical Data
TRAF3, CT (TNF Receptor-associated Factor 3, CAP1, CAP-1, CD40 Receptor-associated Factor 1, CRAF1, CD40-binding Protein, CD40BP, LMP1-associated Protein 1, LAP1)
Tumor necrosis factor (TNF) receptor associated factors (TRAFs) are the major signal transducers for the TNF receptor superfamily and the interleukin-1 receptor:Toll-like receptor (IL-1:TLR) superfamily (1). TRAF3 was first identified by its interaction with CD40 and the Epstein-Barr virus transforming protein LMP1. Several TRAF3 mRNA splice variants exist and some of these can activate the transcription factor NF-?B. Besides CD40, TRAF3 also interacts with the TRFR superfamily member lymphotoxin-? receptor (LT?R) in association with TRAF2 and the apoptosis inhibitors cIAP1 and Smac. It has been suggested that TRAF3 induces mitochondria-mediated apoptosis upon binding of the TNF family cytokine LIGHT by LT?R.
