Hypothesis
Does C-terminal processing of Spt7 occur independently of the SAGA complex?
Conclusion
Truncation of Spt7 happens early in the formation of distinct Spt7 complexes and is not dependent on the SAGA complex.
Supporting Evidence
- C-terminal processing of Spt7 occurs in the absence of SAGA components.
- Truncated forms of Spt7 were observed in yeast strains lacking SAGA components.
- Processing of Spt7 does not require functional Spt7.
Takeaway
The study found that a protein called Spt7 can be cut into smaller pieces even when the complex it usually works with is not functioning, which is surprising.
Methodology
The study involved experiments with yeast strains lacking specific components of the SAGA complex to observe the processing of Spt7.
