From: Evidence for a novel overlapping coding sequence in POLG initiated at a CUG start codon
Mass spectrometry evidence for translation of ORF-Y. a. Predicted translation of human ORF-Y. The CUG initiation codon is presumed to translate to methionine. The two peptides detected by mass spectrometry are colored in blue and red. b. Spectra for the first (red) peptide. c. Spectra for the second (blue) peptide. The sequences of the fragmented ions and their abundances are shown in both b and c
