Ribo-seq profiles of MYC (example of PANTS: AUG and extended CUG proteoforms) and EIF4G2 (example of exclusive non-AUG initiation). Reading frames are colored in red, green, and blue; AUGs (white bars) and stop codons (black bars) are shown within the bottom frame color bars. The asterisk (*) in EIF4G2 represents upstream non-AUG initiation at AUU codon; a downstream out-of-frame short AUG ORF is depicted by a blue arrow; the main ORF (CDS) is shown as a gray bar. In the MYC profile, AUG and CUG proteoforms (main ORFs) are shown as gray bars, and AUG uORFs are shown as red arrows
