NF-kB activity increases when TRAF3 has the homing targets, called ubiquitins, attached to it and is destroyed by the proteasome, a complex of proteins that hunts down ubiquitin-decorated proteins.
When TRAF3 evades attack, it turns that same destructive mechanism against NIK, a protein that is central to NF-kB activity, by tagging it with ubiquitins.
13 /PRNewswire/ -- A protein called TRAF3, with a previously unknown job in immune cells, is actually a key part of a mechanism that triggers release of anti-virus molecules called type I interferons (IFNs) as part of the body's rapid response against these invaders, according to investigators that include a scientist continuing this work at St.
