Fig. 1From: Short open reading frames (sORFs) and microproteins: an update on their identification and validation measuresA comparison between sORF and altORF transcripts in terms of length and initiation codons. A sORF transcript structure with AUG or non-AUG initiation codons, characterised by its short length of 100 codons after post-transcriptional modifications. B altORF transcript structure described with AUG initiation codon, longer than 30 codons and without an upper limit on length, differing from sORFsBack to article page
