Data from: Geometric morphometrics and paleoproteomics in tandem enlighten the paleodiversity of Pongo
<p>This folder contains the data used for the creation of the phylogenetic trees for the manuscript 'Geometric morphometrics and paleoproteomics in tandem enlighten the paleodiversity of Pongo'.</p> <p>Ancient_Sequences.fa is a fasta file containing all palaeoproteomic sequences reconstructed in the context of the above study. (15 fosil pongo samples) </p> <p>'Raw_Reference_Dataset' is a folder containing 9 fasta files. Each fasta contains the reference sequences of multiple samples (6 H.sapiens,27 Pongo, 30 Gorilla, 38 Pan, 2 Macaca, 1 Nomascus, 1 Microcebus, 1 Papio ) for one protein.</p> <p>'Alignments' is a folder containing 9 fasta files with the name of a protein. Each fasta file contains the aligned sequences of the reference dataset and the ancient samples for that protein. Additionally, the fasta file 'CONCATENATED.fa' contains all proteins concatenated, aligned and I/L fixed.</p>
Data from: Peptide sequences from the first Castoroides ohioensis skull and the utility of old museum collections for paleoproteomics
Vertebrate fossils have been collected for hundreds years and are stored in museum collections around the world. These remains provide a readily available resource to search for preserved proteins; however, the vast majority of paleoproteomic studies have focused on relatively recently collected bones with a well-known handling history. Here, we characterize proteins from the nasal turbinates of the first Castoroides ohioensis skull ever discovered. Collected in 1845, this is the oldest museum curated specimen characterized using paleoproteomic tools. Our mass spectrometry analysis detected many collagen I peptides, a peptide from hemoglobin beta, and in vivo and diagenetic post-translational modifications. Additionally, the identified collagen I sequences provide enough resolution to place C. ohioensis within Rodentia. This study illustrates the utility of archived museum specimens for both the recovery of preserved proteins and phylogenetic analyses.
