PELATON (plaque enriched lncRNA in atherosclerotic and inflammatory bowel macrophage regulation) does not encode a micropeptide. A, PELATON predicted open reading frame (ORF; blue) appended with a hemagglutinin (HA) tag (yellow) was inserted into pcDNA 3.1(+) plasmid for in vitro translation assay. LINC00948 was used as a positive control, known to encode the micropeptide MLN (myoregulin). RNA expression using customized primers spanning ORF/HA boundary confirming transcription into RNA from plasmids by (B) quantitative real-time polymerase chain reaction (PCR) and (C) agarose gel electrophoresis of PCR products. D, Western blot using HA-antibody to detect tagged peptide produced by in vitro translation. E, Prediction scores estimating probability of protein-coding potential. M blank+L blank denotes quantitative real-time PCR negative controls for MLN-HA+PELATON ORF-HA, respectively. CPAT indicates coding potential assessment tool; CPC2, coding potential calculator version 2; CSF, codon substituion frequencies; and PRIDE, proteomics identification database.
