Hypothesis
The TBK1 adaptors may form alternative complexes rather than a single large multiprotein complex.
Conclusion
The study suggests that TBK1 does not form a single large multiprotein complex with its adaptors but rather forms alternative complexes with each adaptor.
Supporting Evidence
- TBK1 and IKK-i are pivotal regulators of type-I interferon production.
- TANK, Sintbad, and NAP1 compete for binding to TBK1.
- Deletion or mutation of the coiled-coil 2 region in TBK1 affects its interaction with adaptors.
Takeaway
This study looks at how a protein called TBK1 interacts with other proteins to help the body fight viruses. It finds that TBK1 works with different helpers in different ways.
Methodology
The study used a systematic affinity purification-mass spectrometry approach to derive a comprehensive TBK1/IKK-i molecular network.
Limitations
The study primarily focuses on three adaptors and may not encompass all interactions within the TBK1 network.
