Hypothesis
Can different start codons in the PDE9A gene lead to various protein forms with distinct cellular locations?
Conclusion
The study shows that two start codons in the PDE9A gene can produce different proteins that are localized in various parts of the cell.
Supporting Evidence
- The study identified at least 20 different splice variants of the PDE9A gene.
- Different start codons were shown to produce proteins with varying N-terminal sequences.
- The localization of PDE9A proteins varied significantly among the splice variants.
Takeaway
This research found that the PDE9A gene can make different proteins depending on which starting point is used, and these proteins can be found in different places inside the cell.
Methodology
The study involved expressing different splice variants of PDE9A in HeLa and Cos-1 cells using GFP fusion proteins to analyze start codon usage and protein localization.
