title: Data from: Rapid molecular evolution across amniotes of the IIS/TOR network

description: Comparative analyses of central molecular networks uncover variation that
 can be targeted by biomedical research to develop insights and
 interventions into disease. The insulin/insulin-like signaling and target
 of rapamycin (IIS/TOR) molecular network regulates metabolism, growth, and
 aging. With the development of new molecular resources for reptiles, we
 show that genes in IIS/TOR are rapidly evolving within amniotes (mammals
 and reptiles, including birds). Additionally, we find evidence of natural
 selection that diversified the hormone-receptor binding relationships that
 initiate IIS/TOR signaling. Our results uncover substantial variation in
 the IIS/TOR network within and among amniotes and provide a critical step
 to unlocking information on vertebrate patterns of genetic regulation of
 metabolism, modes of reproduction, and rates of aging.
description: TRANSCRIPTOMES.tarTRANSCRIPTOMES folder includes: (1) The transcriptome assembly for each of the 18 reptile individuals sequenced (e.g. file name: SM1_centroids_nucleotides.fasta), see list below. These contain the longest open reading frames (ORFs) produced by Trinity, which were then clustered by UCLUST into centroids to reduce redundancy within a single species' transcriptome. A centroid may have collapsed multiple isoforms, truncated transcripts, and alleles from a gene, but it may also have collapsed very recent paralogs. Files are named by sequence identifier (e.g. SM) listed below. (2) The Trinotate annotation databases for each transcriptome (e.g. file name: trinotate_annotation_report_SM1.xls). The prot_id corresponds to the centroid sequence in the transcriptome .fasta file. (3) An ortholog key file (Ortholog_Key_3_20_2014.xlsx) that contains a list of each putative ortholog clustered by OrthoMCL, the best blast hit to uniprot, the number of species that were included in the ortholog, and the centroid IDs of those species (corresponding the the transcriptome assembly .fasta files). OrthoMCL was ran on 74 total species, and we excluded form our alignments 8 species with very poor representation (for a maximum of 66 species contained within the alignments analysed for the paper).

The 104,235 putative orthologs described in ALIGNED_ALL-ORTHOLOGS often contained more than two representative sequences per species. For the first 15,000 putative orthologs (those with the most species included in the alignments) we used UCLUST to find the best representative per species per ortholog by taking the sequence that was closest to the centroid for that ortholog. Alignments contain one representative per species per alignment (found by centroid clustering explained in the methods) are given for Orthologs 1-15,000, regardless of how many species are contained in the centroid. After designating one representative sequence per species, alignments were performed as described in the methods (e.g. MSAProbs followed by TranslatorX). Amino acid and nucleotides are given in their respective folders. - Also included in each folder is an ortholog key file (Ortholog_Key_3_20_2014.xlsx) that contains a list of each putative ortholog clustered by OrthoMCL, the best blast hit to uniprot, the number of species that were included in the ortholog, and the centroid IDs of those species (corresponding the the transcriptome assembly .fasta file). OrthoMCL was ran on 74 total species, and we excluded form our alignments 8 species with very poor representation (for a maximum of 66 species contained within the alignments analyzed for the paper).ALIGNED_ALL_ORTHOLOGS.tarALIGNED_ALL_ORTHOLOGS folder: We used OrthoMCL to cluster ORF-centroids from all species into putative orthologs from all the species included in this study. This folder contains the putative ortholog amino acid alignments and corresponding nucleotide alignments for which there were two or more species present in the ortholog clustered by OrthoMCL (104,235 total alignments). These are available as separate files for each ortholog (104,235 total orthologs with two or more species). Amino acid and nucleotides are given in their respective folders. - Also included is an ortholog key file (Ortholog_Key_3_20_2014.xlsx) that contains a list of each putative ortholog clustered by OrthoMCL, the best blast hit to uniprot, the number of species that were included in the ortholog, and the centroid IDs of those species (corresponding the the transcriptome assembly .fasta file).

This folder also contains an excel file with the annotation for the IIS/TOR test genes.Species.IdentifierSpecies.Identifiers file. For the species included in this study this file contains the (i) Sequence Identifier (for the transcriptomes we developed) or the Ensemble identifier (for the genomes and transcriptomes we downloaded); (2) the species name; (3) the common name; (4) any "nicknames" that were used during the analysis, and (5) the identifiers used in the alignments.
