Proteins are robust molecules that are made up of chains of amino acids, their sequences are dictated by their gene’s DNA sequence. Yet some proteins are much more robust than DNA.
They are known to survive for millions of years and may be a vital resource of genetic information in extinct species far beyond the limits of ancient DNA analysis.
We have three main research interests that utilise ‘palaeoproteins’:
Phylogenetic reconstructions using ancient sequences
Understanding biomolecule diagenesis
Species Identification (Zooarchaeology by Mass Spectrometry; ZooMS)
