Hypothesis
Concentration-dependent trypsin digestion will change as a function of phosphorylation state of HDAC1.
Conclusion
Phosphorylation of S421 and S423 individually contributes to HDAC1 function, and associated proteins promote its enzymatic activity.
Supporting Evidence
- HDAC1 phosphorylation at S421 and S423 is crucial for its function.
- Limited proteolysis studies suggest that HDAC1 does not have distinct protease-resistant regions.
- Phosphorylation promotes HDAC1's interaction with associated proteins.
Takeaway
This study looked at how a protein called HDAC1 works and found that two specific parts of it need to be changed for it to do its job properly.
Methodology
Limited proteolysis experiments were performed using trypsin on HDAC1 isolated from human Jurkat cells.
Limitations
The study does not provide insights into the structural details of HDAC1 due to challenges in isolating it in active form.
