Hypothesis
The study investigates the presence of distinct genes at the TRPC2 locus in marsupials and monotremes.
Conclusion
The study identifies two distinct genes, XNDR and TRPC2, at the TRPC2 locus, with XNDR having a role in DNA repair and TRPC2 being specifically expressed in the vomeronasal organ.
Supporting Evidence
- TRPC2 is specifically expressed in the vomeronasal organ of the tammar wallaby.
- XNDR is widely expressed in many tissues, suggesting a role in DNA repair.
- Strong expression of TRPC2 was detected only after about day 30 post-partum.
Takeaway
Scientists found two different genes in a specific area of DNA that were thought to be one. One gene helps with smelling, and the other might help fix DNA.
Methodology
The study used cDNA cloning, expression analysis, and bioinformatics to analyze the TRPC2 locus in marsupials and monotremes.
