Study using novel protein purification strategy shows that TRAF3 triggers interferon release while curbing inflammation, according to St. Jude
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 bodys rapid response against these invaders, according to investigators that include a scientist continuing this work at St. Jude Childrens Research Hospital.
The discovery of TRAF3s role helps to explain how immune cells called macrophages use sensing devices called Toll-like receptors (TLRs) to orchestrate just the right response to different types of infections. TLRs are on the outer membranes of macrophages and respond to germs by triggering the production of proteins called cytokines. Various cytokines regulate different biological functions that are important during immune responses, such as inflammation and protection against viruses. In addition, some cytokines contain anti-inflammatory activities, which curb potentially harmful inflammation.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
