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 (1,2,3,4), in contrast to ordinary SNPs at positions of low conservation. Thus phyloSNPs are informative to the distinctive biology of the species carrying them and suggest a focus for subsequent experiment.
It is also of particular interest to determine the levels of variation within the Tasmanian devil population as a whole because the number of individuals have become low and possibly inbreed with adverse sequelae. For this it will be necessary to first determine sites of variation and then to genotype them across a large number of individuals.
Marsupial genomic and cDNA data to date has been quite limited compared to placental mammal. Yet as outgroup, metatheran animals provide important context to placentals and represent important context in understanding human protein evolution. The monotheres are inevitably limited by the paucity of extant species (basically platypus and echidna) and dim prospects for fossil DNA. Consequently echidna provides an important adjunct to the existing but incomplete platypus assembly. While extant birds and reptiles -- the preceding divergence node -- are abundant it must be remembered that a very considerable time elapsed (from 310 mry to 175 mry) prior to divergence of mammals with living representatives. This gap of 135 myr is comparable to the whole evolutionary record of theran mammals.
Assumed vertebrate phylogenetic tree
Marsupial relationships taken from 2009 paper establishing the mitochondrial genome sequence of the Tasmanian tiger (Thylacinus cynocephalus):

Phylo-sorting data
This tab-delimited table enables four different sort orders. These are needed because data can be missing from species in a manner that varies by gene, making data alignment difficult. Some alignment tools also lose input order, so that needs to be recovered. The ordering here flattens the phylogenetic tree by taking human (arbitrarily) at the top and resolving ambiguous situations (eg mouse, rat) by putting species with the best assemblies first.
The first two columns provide sort order number for the 44 species alignment at UCSC as phylogenetic and alphabetic order respectively. The third and fifth columns do this for a larger set of species for which data is commonly available. The fourth column provides a fasta line indicator. The sixth column is a dummy gene name to be replaced as needed. The next column has stripped out the syntax from Newick tree format. This column and column six together will correctly draw the vertebrate phylogenetic tree in all online software without further editing. The final columns provide genus, species, and common name.

Candidate analysis
The first issue is error within the reads themselves; the second is whether the default 454 Newbler assembler correctly identified overelapping reads and put them together properly to give exon-spanning reads. Those issues are discussed elsewhere -- here it is assumed the data is correct, so the entire focus is on subsequent bioinformatics.

Read data format: the top row gives project gene name, HGNC gene name and exon number from ENSEMBL monDom5
and human orthology predictions, then Monodelphis amino-acid segment, then sequence differences in
tasmanian devil (in this case, both individuals differ from Monodelphis by L->F), then differences between the two thylacines
(here one individual has R at position 15, the other has H), and finally the number of experimental reads that confirm the nucleotide
difference and the sum of the quality scores. The sequences were assembled by Newbler (the official 454 assembler) which uses
lower-case letters for less confident calls.
Pseudogene issues: ERN2 has not generated potentially confusing recent processed pseudogenes in mammals (lack of human, opossum or platypus genome Blat matches to ERN2 query). The variation observed here between individual tasmanian devils is implausibly an early stage in the loss of parent gene because of ERN2 functional essentiality; the exon cannot come from a decaying segmental duplication because coverage is high enough to also detect the main gene.
Paralog issues: The GeneSorter tool at UCSC shows a single significant full-length paralog in human, ERN1, also with 22 coding exons. The genes reside on different chromosomes but in regions with local homology of synteny. However this particular exon is a good match (3 differences out of 23), so there is potential for experimental difficulties in distinguishing them in short reads (including the following exon readily resolves them bioinformatically). In any event, at positions 15 and 20, ERN1 is identical at the amino acid level to ERN2. The gene duplication appears to have occured subsequent to amphioxus divergence earlier diverging metazoans are single-copy.
Homoplasy (recurrent mutation) issues: This exon is very conserved and does not exhibit repetitive sequence, compositional simplicity, or indels in any species in either paralog that could foster experimental error or alignment ambiguity. At position 15, the ancestral value is arginine in both paralogs. The G--> A transition to histidine in one individual is conservative under most circumstances (still basic) and arises from an arginine codon CpG hotspot conserved back to lamprey in 30 of 32 species with available data, yet histidine is not observed part of a reduced alphabet (ie R/H) at this position over many billions of years of branch length. Consequently R-->H is a significant change in this individual tasmanian devil.
Known variations: No human disease variants have been reported for either ERN2 or ERN1, probably attributable to essentiality. Site-specific mutation close to the exon here have been generated for K121P, D123P, W125A, and Q105E but only for ERN1. Naturally occuring coding SNPs in the human population relevent to the ERN2 exon are not known but low frequency alleles could emerge from the 1000 Genomes Project.
Side issues: a very ancient conserved leucine at position 21 appears to be transitioning to phenylalanine at marsupial node but has not been fixed, so settles out as L or F depending on lineage-sorting on each terminal marsupial leaf whereas placentals are all changed to phenylalanine (a phyloSNP caught in mid-air). While L and F might seem about the 'same' as amino acids, the branch length conservation totals say both are important but for different reasons: this is not a waffle codon nor reduced alphabet situation. This raises the question -- given the extreme conservation of this exon otherwise -- of whether the L-->F change at position 21 in both individuals has 'enabled' (made neutral or adaptive) an otherwise unfavorable R-->H change at position 15 in one individual.
Structural significance: By good fortune, the crystal structure of ERN1 (alternately called IRE1) has been published. The PDB 2HZ6 structure has good coverage of this particular exon. Consequently the marsupial ERN2 could be very accurately modelled and the structural effects of L-->F with or without R-->H computed by submission to online SwissProt modelling service.

Functional significance: A considerable amount is known about the paralog ERN1. Annotation transfer is likely applicable to ERN2. The two gene products differ primarily in expression -- ERN1 ubiquitious but ERN2 restricted to intestinal epithelial cells:
"The unfolded protein response (UPR) is an evolutionarily conserved mechanism by which all eukaryotic cells adapt to the accumulation of unfolded proteins in the endoplasmic reticulum (ER). Inositol-requiring kinase 1 (IRE1 or ERN1) and PKR-related ER kinase (PERK) are two type I transmembrane ER-localized protein kinase receptors that signal the UPR through a process that involves homodimerization and autophosphorylation... The monomer of the luminal domain comprises a unique fold of a triangular assembly of beta-sheet clusters. Structural analysis identified an extensive dimerization interface stabilized by hydrogen bonds and hydrophobic interactions... Mutations that disrupt the dimerization interface produced ERN1 protein that failed to either dimerize or activate the UPR upon ER stress."
"ERN1 is a type I transmembrane protein kinase receptor that also has a site-specific RNase activity that, upon activation, initiates a site-specific unconventional splicing reaction. The substrate for IRE1 RNase in metazoans is Xbp1 mRNA, which encodes a basic leucine zipper transcription factor of the ATF/CREB family. XBP1 controls expression of genes containing an X-box element or a UPR element in their promoter regions. The IRE1-mediated splicing reaction introduces into XBP1 an alternative C terminus, thereby generating an XBP1 molecule that is a more potent transcriptional activator. Therefore, activation of IRE1 and its RNase increases the transcription of genes encoding ER chaperones and folding catalysts... the ERN1 N-terminal luminal domain (NLD) functions as an ER stress sensor... under normal conditions IRE1 is maintained in a monomeric state through interaction of the NLD with the ER resident chaperone BiP. Upon ER stress, Grp78 binds to unfolded proteins as they accumulate, permitting the released NLD to form homodimers. Dimerization of the NLD in turn leads to the activation of the protein kinase and RNase activities in the cytosolic domain of ERN1."
ENR2 is readily distinguished from its ERN1 paralog at tBlastn by including the two following exons which bring percent identity to 62%:

Read data format: the top row gives project gene name, HGNC gene name and exon number from ENSEMBL monDom5
and human orthology predictions, then Monodelphis amino-acid segment, then sequence differences in two
tasmanian devil (here one is identical and the other differs from Monodelphis by C->Y) and finally the number of experimental reads that confirm the nucleotide
difference and the sum of the quality scores. The sequences were assembled by Newbler (the official 454 assembler).
Pseudogene issues: No processed pseudogenes relevent to this exon are seen by Blat of human and opossum sequence. Some questionable sequence occurs in tarsier and sloth but may be due to low coverage read or assembly error. These fragmentary sequences also have cysteine at the position in question.
Paralog issues: This gene has a moderately similar paralgog, MGAT5B, with a similar enzymatic role (beta1,6-N-acetylglucosaminyltransferase). The opossum MGAT5B protein differs at 12 positions out of 49 from opossum MGAT5, whereas human and marsupial MGAT5A differ at one residue. Consequently the two paralogs are readily distinguished within vertebrates. This is moot because 33 of 33 available MGAT5B also have cysteine at the position in question (data not shown).
Homoplasy (recurrent mutation) issues: The alignments below show tyrosine has never replaced cysteine in any other species. This cysteine is extremely invariant in both paralogs, tracing back to lophotrochozoa and cnidaria.
Known variations: No human disease alleles have been mapped to either paralog. None of 9 SNP tracks at the UCSC browser show human variatin in this exon.
Side issues: The column marked with an asterisk in the difference alignment below indicates a non-conservative phyloSNP K-->I that occured in the theran mammal stem after platypus divergence. All three marsupial sequences including tasmanian devil have isoleucine in this position as do all 30 of the available placental mammal sequences, suggesting that both the lysine and the isoleucine continue to be under strong selection. No comparable shift occured in the theran stem for MGAT5B where the residue is arginine in all species, a basic residue similar to lysine.
Structural significance: The MGAT5 gene encodes a conventional enzyme, mannosyl (alpha-1,6-)-glycoprotein beta-1,6-N-acetyl-glucosaminyltransferase, a glycosyltransferase involved in the synthesis of protein-bound and lipid-bound oligosaccharides. Surprisingly, no determined 3D structure exists at PDB at this time that is relevent to the configuration of this exon -- nor indeed the 741 residue protein. Only small regions of the protein have a prediction at ModBase.
SwissProt does not annotate the cysteine at position 532 as part of a disulfide or active site; the predicted location (Golgi) can have homodimer disulfides of similar enzymes, though this is a complex topic. Highest MGAT5 expression occurs in brain, heart, kidney, and placenta. No domains other than a signal peptide and 6 of its own glycosylation target sites are found by online tools such as SMART.
Although the bulky tyrosine substitution is conservative in the sense of polar nature and perhaps hydrogen-bonding capacity, it cannot replace these specialized functions of cysteine. Considering the extreme conservation of this cysteine, this substitution must have a substantial-- perhaps even disabling -- impact on enzymatic function.
Functional significance: In view of the facial tumor situation in tasmanian devils, OMIM's account of prior research in mouse on this gene is quite interesting. Less is known about MGAT5B though it also functions in the synthesis of complex cell surface N-glycans.
" Malignant transformation is accompanied by increased beta-1,6-GlcNAc branching of N-glycans attached to Asn-X-Ser/Thr sequences in mature glycoproteins... The amount of MGAT5 products correlates with disease progression... Mgat5-deficient mice, which are born healthy but develop various abnormalities as adults...Mgat5-deficient mice showed kidney autoimmune disease, enhanced delayed-type hypersensitivity, and increased susceptibility to experimental autoimmune encephalomyelitis...The Golgi enzyme beta1,6 N-acetylglucosaminyltransferase V (Mgat5) is up-regulated in carcinomas and promotes the substitution of N-glycan with poly N-acetyllactosamine, the preferred ligand for galectin-3 (Gal-3)...inhibitors of MGAT5 might be useful in the treatment of malignancies by targeting their dependency on focal adhesion signaling for growth and metastasis."

Other marsupial genes of interest
The collections below contain well-understood genes with very extensive comparative genomics. They can serve as a test bed for Sarcophilus assembly quality, a place where genuine anomalies or distinct adaptive features might surface (perhaps as phyloSNPs) and where marsupial phylogeny might be refined using rare genomic events in nuclear genes.
The gene sets contain all available marsupial orthologs plus for context one flanking gene each from placentals and monotremes. These genes are available in much broader hand-curated sets elsewhere on this site.
Rod rhodopsin RHO1 (4 marsupials)
The optimal wavelength for scotopic (dim light) vision of Sarcophilus is easily predictable provided key tuning residues are covered by the assembly.

Cone rhodopsin SWS2 (9 marsupials)
Cone rhodopsin RHO2 has been lost in all mammals and no debris from this gene is expected in Sacrophilus). The short wavelength cone opsin SWS2, while still present in platypus, has also been lost in all theran opsion too long ago to leave detectable remnants in syntenic position. Cone opsin SWS1 has this turned around, being present in theran mammals but only as debris in platypus.

Cone rhodopsin LWS (9 marsupials)
This basal imaging opsin is available from 97 vertebrates and has already been analyzed for phyloSNPs and rare genomic events. The Didelphimorphia experienced a 3-4 residue insert in exon 1 that separates them from all other marsupials. Note this region has quite a complicated indel history. The extra residues have repeat character DVNE DDND suggesting replication slippage.

Encephalopsin (2 marsupials)
Encephalopsin has a very peculiar history of gene loss in tetrapods, requiring some seven independent events. While this limits the phylogenetic utility of gene loss within marsupials, it is still of interest to determine the status of the gene within Sarcophilus.
