Constructs generated to validate the protein-coding potential of small open reading frames. The 5′UTR-ORFs of glyceraldehyde 3-phosphate dehydrogenase, ZFAS1, SNHG8, and RP11-879F14.2 were fused to a GFPmut in which the green fluorescent protein start codon ATGGTG was mutated to ATTGTT. Substantial amounts of fusion protein were detected following transfection of the constructs into SK-Hep1 cells. In addition, the fusion protein was abolished after SK-Hep1 cells were transfected with the GFPmut construct.
