  1. ...sitesA eukaryotic gene typically consists of regulatory elements such as distal enhancers, which can act over long distances; a proximal promoter containing key TF binding sites; a core promoter surrounding the transcription start site (TSS) where the preinitiation complex assembles, followed...

  2. ...(lower). ChEC-seq signal is the 5′ end of reads, presented in purple. Nucleosome occupancy data of the hybrid (Tirosh et al. 2010) are presented as gray lines. Transcription start sites are presented in gray dashed lines (Pelechano et al. 2013; Park et al. 2014). For Swi5, CCAGC motif sequences...
  3. ...: ettwiller@neb.comAbstractDetermination of eukaryotic transcription start sites (TSSs) has been based on methods that require the cap structure at the 5′ end of transcripts derived from Pol II RNA polymerase. Consequently, these methods do not reveal TSSs derived from the other RNA polymerases that also play...
  4. ...-mRNA expression (pre-mRNA), MYC signal at transcription start sites (MYC TSS Share), RNA Pol II signal at transcription start sites (RNAP_TSS), gene body regions (RNAP_GB), transcription end sites (RNAP_TES), mRNA expression (mature), synthesis rates (synthesis), degradation rates (degradation), and processing...
  5. ...in biology. Transcription start sites (TSSs) are especially interesting because they are central to initiating gene expression. Previous studies revealed widespread transcription initiation and fast turnover of TSSs in mammalian s. Yet, how new TSSs originate and how they evolve over time remain poorly...
  6. ...genes with NCBI RefSeq transcript ID that start with NM_ or NR_ are considered), which include 3297 out of 4781 (69%) housekeeping genes previously reported (Li et al. 2017). The number of strong enhancers associated with the 6107 genes are 8281 and 6756 in ESCs and MEF cells, respectively. The number...
  7. ...poorly understood.Mammalian spermatogenic cells represent an exceptional system to discover the in vivo nuclear contributions of AGO2. As mature sperm develop in mammals, the undergoes extensive chromatin reorganization and uses distinct mechanisms of transcriptional regulation. During meiosis...
  8. ...of miR-7 by the Oip5os1 (also known as Cyrano) long noncoding RNA (lncRNA) in mammalian tissues (Kleaveland et al. 2018).Questions also remain regarding the rates of miRNA turnover and the extent to which degradation is regulated in a miRNA-specific manner. Most miRNAs that have been examined are highly...

  10. .... When compared with Conserved and Shifted core promoters, Turnover core promoters tended to show lower transcriptional activity (Fig. 5B) and usually were located at further upstream of the translation start codons (Fig. 5C).We examined the genomic sequences from −20 to +20 bp surrounding the dominant...
