A screenshot depicting the mapping of mass spectrometry-derived peptide sequence data onto the genome sequence in 'ContigView' of Ensembl Genome Browser. The red rectangles on 'MS data JHU' track are peptide sequences obtained through tandem mass spectrometry. The brown colored rectangles on the 'Ensembl trans.' are the Ensembl known transcripts. Ten peptides are shown to match two exons in the known transcript encoding D7-related protein 1. The prefix JHU refers to Johns Hopkins University and is followed by a unique identifier for each peptide. Clicking on the peptide accession number links to a page http://pandeylab.igm.jhmi.edu/MS-DAS/Anophelesgambiae webcite containing additional information including its sequence.
