TNF receptor associated factors
tnf receptor associated factors
TNF receptor associated factors also known as TRAFs are a family of proteins primarily involved in the regulation of inflammation, antiviral responses and apoptosis.   Currently, seven TRAF proteins have been characterized in mammals : TRAF1, TRAF2, TRAF3, TRAF4, TRAF5, TRAF6 and TRAF7.  Except for TRAF7, these proteins share a relatively conserved secondary structure, including a namesake C-terminal TRAF domain that mediates interactions with other signaling components such as the transmembrane TNF receptors and CD40.
