Figure 2.

Peptide sequences mapped to a genomic region. Several peptides fall within an annotated gene locus, validating translation of two exons and an intron. One peptide indicates a novel splice isoform which skips the internal exon. Additional peptides fall within an annotated pseudogene giving strong indication for its translation in the cell. Peptides which fall within the intergenic region may indicate novel protein-coding loci. Cyan colored peptides would likely not be identified using a standard proteomic database.
