The genome of Schmidtea mediterranea is sequenced but mostly un-annotated making it a prime candidate for genome-based peptide fingerprint scanning. When the proteins were analyzed with GFS 1,604 proteins were identified. These proteins had mostly not been annotated before they were found with GFS They were also able to find the mucous subproteome (all the genes associated with mucus production).
The genome of Schmidtea mediterranea has been sequenced but lacks annotations, making it a suitable subject for using peptide fingerprint scanning to identify proteins and their functions.  This approach led to the discovery of 1,604 previously unknown proteins and the identification of the mucous subproteome.
