Toolkit/BX795 perturbation of TBK1 signaling
BX795 perturbation of TBK1 signaling
Also known as: BX795, TBK1 inhibitor BX795
Taxonomy: Technique Branch / Method. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Using the TBK1 inhibitor, BX795, we discovered that HBsAg-enhanced TBK1 dimerization, promoting sequestosome-1 (p62) phosphorylation, was necessary for HBV-induced autophagy and HBV replication.
Usefulness & Problems
Why this is useful
BX795 is used here as a TBK1 inhibitor to test whether HBsAg-enhanced TBK1 dimerization and downstream p62 phosphorylation are required for HBV-induced autophagy and replication.; probing TBK1 dependence of HBsAg-associated autophagy and replication phenotypes; mechanistic perturbation of TBK1-linked signaling

This approach requires BX795 treatment in the experimental system and readouts for TBK1-linked signaling, autophagy, or replication. The abstract does not provide dosing or protocol details.; requires pharmacologic inhibitor treatment in the relevant experimental system
The abstract does not establish whether BX795 alone resolves all pathway specificity questions or separates dimerization from kinase activity in detail.; the abstract does not report dose, selectivity details, or assay conditions
