Previous studies have predicted thousands of ORFs in five prime'UTRs  the vast majority of which have unknown function. We present a systematic analysis of the translation and function of upstream open reading framesuORFs across vertebrates. Combining high resolution ribosome footprinting and phasing  we find that i uORFs are pervasive within vertebrate transcriptomes  ii the majority show signatures of active translation  and iii uORFs act as potent regulators of translation and RNA levels  with a similar magnitude to miRNAs. Evolution has targeted sequence features to mitigate the effects of constitutively repressive uORFs. Finally  we observe that the regulatory potential of uORFs on individual genes is conserved across species. These results provide insight into the regulatory code within mRNA leader sequences and their capacity to modulate translation across vertebrates.The mRNA seq data contained in this archive were used along with ribosome profiling data to calculate translation efficiency values.", null, null, null, "12hpf", "AG00434 mrna r0 12h", null, "strain:TUAB|age:12hpf|sex:pooled male and female|tissue:embryo|genotype:wt|BioSampleModel:Model organism or animal", null, null, null, null, null, null, null, null, "AG00434 mrna r0 12h", "12h mRNA R0", "1", "Twenty embryos per condition were collected from the same clutch from where the ribosome profiling timeseries was conducted.Bazzini et al  2014 Total RNA was isolated using 1mL of Trizol following manufacturer instructions.
