Marsupial phyloSNPs
Introduction to Marsupial phyloSNPs
In this project, new genomic data from the Tasmanian devil (Sarcophilus harrisii), Tasmanian tiger (Thylacinus cynocephalus), and echidna (Tachyglossus aculeatus) are analyzed for significant changes at the protein coding level. The goal is to find single amino acid changes in one of these species at a highly invariant residue in a well-conserved exon in a gene with known or predictable tertiary structure. Such changes are thought to enrich for genetic changes with significant, adaptive biochemical or phenotypic consequences ([[Opsin_evolution:_RGR_phyloSNPs#PhyloSNPs_in_RGR|1],[[Opsin_evolution:_RGR_phyloSNPs#PhyloSNPs_in_RGR|2][[Opsin_evolution:_RGR_phyloSNPs#PhyloSNPs_in_RGR|3],[[Opsin_evolution:_LWS_PhyloSNPs#PhyloSNPs_in_LWS_opsins:_alignment_of_94_LWS_vertebrate_opsins|4]), in contrast to ordinary SNPs at positions of low conservation.
