Survey of cryptic unstable transcripts in yeast

Project description:We sequenced both the stable (WT) and unstable (rrp6delta) transcriptomes of three S.cerevisiae strains: S288c, Σ1278b, JAY291 and the S.paradoxus strain N17 for de novo annotation of cryptic unstable transcripts (CUTs). Doing so we have greatly expanded on previous CUTs which were limited to the S.cerevisiae strain S288c and have provided the first assessment of CUT expression conservation in yeast

Detection of cryptic unstable transcripts associated with ribosomes in yeast

Project description:We investigated the association of cryptic unstable transcripts (CUTs) to ribosomes in Saccharomyces cerevisiae. We used 5’cap-sequence followed by sucrose gradient fractionation of polyribosome fractions after ultracentrifugation to assess the relative association of transcripts to the ribosomes. We used 5PSeq approach, which measures ribosome dynamics by sequencing the presence of co-translation mRNA degradation intermediates, to assess if cryptic transcripts are engaged in active translation. We performed 5PSeq after glucose depletion to increase the number of ribosomes stop at the 5’UTR and start codon.

Transcription profiling of wild type yeast grown with ethanol, glucose and galactose and the deletion mutant of Rrp6 to identify transcription start and end positions

Project description:To obtain a comprehensive survey of the structure and expression level of transcripts across the yeast genome, we used tiling arrays to profile wild-type transcriptomes in ethanol (YPE), glucose (YPD, SDC), and galactose (YPGal), which together encompass the main laboratory growth conditions of yeast. Transcript start and end positions were mapped to the genome by a segmentation algorithm and subsequent manual curation. To identify Cryptic Unstable Transcripts (CUTs), profiles were also measured for a deletion mutant of Rrp6, an important component of the nuclear exosome, which is involved in the degradation of CUTs. Expression profiles are provided in a searchable web-database (http://steinmetzlab.embl.de/NFRsharing).

Chromatin-dependent cryptic promoters encode alternative protein isoforms in yeast

Project description:Cryptic 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 usage, chromatin organization and post-transcriptional consequences in Saccharomyces cerevisiae. We show that transcription start sites of chromatin-dependent internal cryptic transcripts resemble those of protein coding genes in terms of DNA sequence, directionality and chromatin accessibility. We define the 5’ and 3’ boundaries of cryptic transcripts and show that, contrary to RNA degradation-dependent ones , they often overlap with the end of the gene thereby using the canonical polyadenylation site and associate to polyribosomes. In fact, we show that chromatin-dependent cryptic transcripts can be recognized by ribosomes and may produce truncated polypeptides from downstream, in-frame start codons. Our work suggests that a significant fraction of chromatin-dependent internal cryptic promoters are in fact alternative truncated mRNA isoforms. The expression of these chromatin-dependent isoforms is conserved from yeast to human expanding the functional consequences of cryptic transcription and proteome complexity.
