Hypothesis
We hypothesized that RAMA acts as an escorter for RAP1 to recruit RAP1, −2 and −3 into a rhoptry-destined protein complex.
Conclusion
The study provides evidence of a novel mechanism for trafficking of proteins to the rhoptries in the malaria parasite.
Supporting Evidence
- RAP1 is localised in the rhoptry bulb and contains distinct signals for localisation within the organelle.
- RAMA interacts with RAP1 to facilitate its targeting to the rhoptries.
- The study identifies a bipartite rhoptry targeting signal within RAP1.
Takeaway
This study looks at how a protein called RAP1 gets to a special part of the malaria parasite called the rhoptry, which helps the parasite invade cells.
Methodology
The study used green fluorescent protein chimeras and in vitro pull-down assays to analyze the signals required for trafficking of the rhoptry protein RAP1.
