Hypothesis
The study aims to identify mRNA targets for specific RNA-binding proteins in Trypanosoma cruzi.
Conclusion
Functionally related transcripts were preferentially associated with specific RNA-binding proteins, suggesting coordinated control of mRNA subsets at the post-transcriptional level.
Supporting Evidence
- Two RNA-binding proteins, TcUBP1 and TcRBP3, were identified as having specific mRNA targets.
- Signature RNA motifs were found in the 3'-UTRs of target transcripts.
- Both proteins can share target transcripts but preferentially bind to different sets.
Takeaway
The study found that certain proteins in trypanosomes stick to specific parts of RNA, helping to control how genes are expressed.
Methodology
The study used immunoprecipitation assays to identify mRNA targets for two RNA-binding proteins, followed by RNA extraction and analysis.
