WebDec 17, 2015 · A comparison of the enrichment of the different classes of cryptic transcripts for the 1.5 and 5 min labeling times relative to the total RNA samples indicated that CUTs, SUTs and XUTs were all readily detected and decayed more slowly than intron-containing transcripts and snoRNAs (Fig. 2a, Table 1, Additional file 1: Figure S1).
WebWe also focus on the molecular mechanisms that cells exploit to prevent cryptic transcripts from interfering with the expression of protein-coding genes. Finally, we summarize data obtained in different systems suggesting that such RNAs may play a critical role in the regulation of gene expression as well as the evolution of genomes.

WebCryptic transcription is widespread and generates a heterogeneous group of RNA molecules of unknown function. To improve our understanding of cryptic transcription, we investigated their transcription start site (TSS) usage, chromatin organization, and posttranscriptional consequences in Saccharomyces cerevisiae We show that TSSs of …
WebMar 19, 2009 · The authors then predicted the occurrence of cryptic transcripts by comparing the ratio of probe values measured at the 5′ end of the gene to the ratio of probe values at the 3′ end of the gene. A higher ratio at the 3′ end indicated an aberrant transcript that initiated somewhere downstream of the natural 5′ promoter.
