Dana holds a 59% operating interest in Platypus, which was discovered by the oil and gas explorer in 2010.
Finding specimens was difficult because access to platypus habitats required back-country travel, and moreover, once in platypus country, the stealthy, shy platypus was difficult to sight and even more difficult to capture, alive or dead.
In non-placental mammals there is one member in platypus and two in opossum.
It is currently not clear whether the KLK skin cascade emerged in platypus, since we were unable to identify a KLK7 orthologue in platypus but this may be due to incomplete genome sequencing.
There is no Sry in fish and it is clearly absent in Platypus, Chicken, Zebrafinch, Anolis, Xenopus and all the fish genomes [7], [8].
The first intron was probably introduced in the very early mammalian evolution because it is found in platypus, marsupial and other mammalian but not in avian V2R genes.
We found that corneodesmosin, desmoglein and desmocollin are present in platypus (ABU86923, XP_001515334 and XP_001515354, respectively) but in frogs only desmocollin was found (NP_001122136).
In platypus, the interpretation could be the same.
In platypus alignment of this region is not possible (not shown).
First, we identified orthologous genes, in platypus and chicken, to the human mt-N genes.
Similar features could exist in platypus, for which also only AMTN gDNA is available.
