Hypothesis
The UPF0201 family of proteins may have a novel function in archaebacteria despite their structural similarity to RNA-binding proteins.
Conclusion
The study found that UPF0201 proteins share a common structural fold with RNA-binding proteins but likely do not function as RNA-binding proteins.
Supporting Evidence
- The structures of UPF0201 proteins were determined using X-ray crystallography.
- Despite low sequence similarity, the proteins share a common structural fold.
- The study suggests that UPF0201 proteins likely do not function as RNA-binding proteins.
Takeaway
Scientists looked at some proteins from ancient microbes and found they look like proteins that bind RNA, but they probably don't do that job.
Methodology
X-ray crystallography was used to determine the structures of four UPF0201 proteins.
Limitations
The study does not confirm the exact functions of the UPF0201 proteins, which remain unknown.
