Author(s): Zwaenepoel Karen, Louis Justin V, Goris Jozef, Janssens Veerle
Primary Institution: K.U. Leuven
Hypothesis
The study investigates the genomic organization, developmental regulation, and distribution of murine PR72/B" subunits of protein phosphatase 2A.
Conclusion
The murine PR72/B" family exhibits significant diversity and evolutionary divergence compared to human orthologues, with implications for future research on knockout mice.
Supporting Evidence
- The study identified three genes encoding nine isoforms of murine PR72/B" subunits.
- All subunits are highly expressed in heart, indicating a significant role in cardiac function.
- The research provides a framework for generating PR72/B" knockout mice for further studies.
Takeaway
This study looks at different parts of a protein that helps control cell functions in mice, showing that they are quite different from similar proteins in humans.
Methodology
The study involved deducing sequences, genomic organization, and expression analysis of murine PR72/B" isoforms using techniques like Northern blotting and immunohistochemistry.
Limitations
The study does not confirm the existence of all predicted isoforms at the mRNA or protein level, suggesting some may be poorly expressed or result from splicing errors.
