Hypothesis
YopH should have a wide specificity to target a broad range of proteins involved in immune response.
Conclusion
YopH interacts with several proteins involved in immune signaling pathways, selectively dephosphorylating some while binding to others.
Supporting Evidence
- YopH binds to Gab1, Gab2, p85, and Vav, indicating a broad interaction with immune signaling proteins.
- Only p85 was dephosphorylated by YopH, suggesting selective targeting.
- YopH's ability to bind to adaptors like Gab1 and Gab2 may help it localize to signaling complexes.
Takeaway
YopH is a protein that helps the plague bacteria hide from the immune system by sticking to important proteins in our body's defense.
Methodology
Biochemical experiments including pull-down assays and dephosphorylation assays were conducted to study YopH interactions.
Limitations
The study may not cover all potential substrates of YopH due to the complexity of immune signaling pathways.
