  • The research, titled "Circadian ribosome profiling reveals a role for the Period2 upstream open reading frame in sleep," to be published in PNAS , redefines our understanding of how translation and post-transcriptional processes influence the body's internal clock and its impact on sleep patterns. (eurekalert.org)
  • And by trying to answer this basic timing question, we found that ribosomes bind an upstream open reading frame in Period2 which altered the amplitude of circadian rhythms and disrupted sleep in mice," adds lead author Arthur Millius. (eurekalert.org)
  • In the context of gene finding, the start-stop definition of an ORF therefore only applies to spliced mRNAs, not genomic DNA, since introns may contain stop codons and/or cause shifts between reading frames. (wikipedia.org)
  • By itself even a long open reading frame is not conclusive evidence for the presence of a gene. (wikipedia.org)
  • An additional open reading frame (ORF), AL4, lies within the essential AL1 gene. (ncsu.edu)
  • Within LR promoter sequences, a small open reading frame (ORF) was identified (ORF-E) that is antisense to the LR-RNA, and downstream of the bICP0 gene. (nebraska.edu)
  • When examining an unknown DNA sequence, one indication that it may be part of a gene is the presence of an open reading frame or ORF. (genome.gov)
