Hypothesis
We hypothesize that R22, R133, and R135 can be useful peptide substrates for ROCK2.
Conclusion
The study identified three peptide substrates (R22, R133, and R135) that are useful for ROCK2, which could aid in drug development.
Supporting Evidence
- The study synthesized 136 peptide substrates from protein substrates for ROCK2.
- Five peptide substrates showed high CPM values for ROCK2.
- R22, R133, and R135 displayed the highest CPM levels for ROCK2 compared to other enzymes.
Takeaway
The researchers made 136 small pieces of proteins to see which ones could be used by a specific enzyme called ROCK2, and they found three that worked really well.
Methodology
The study synthesized 136 peptide substrates and analyzed their phosphorylation by ROCK2 using a radiolabel assay.
Limitations
Different experimental methods make selecting substrates for ROCK2 quite difficult.
