  • I used Parallel Analysis of RNA Ends (PARE) to identify other mRNA substrates of TSEN. (tmc.edu)
  • Meiotic recombination is initiated by programmed DNA double-strand breaks (DSBs), generated by SPO11 and accessory proteins (de Massy 2013 ). (springer.com)
  • In this strain, 1 putative cleavage site of the viral polyprotein responsible for processing of structural proteins was changed. (cdc.gov)
  • Using next generation sequencing, we have characterized the major classes of small RNAs, micro (mi) RNAs, piwi interacting (pi) RNAs, and the centromere repeat associated short interacting (crasi) RNAs in the tammar. (biomedcentral.com)
  • A survey of the tammar gonadal piRNAs shows that these small RNAs are enriched in retroelements and carry members from both marsupial and tammar-specific repeat classes. (biomedcentral.com)
  • These small RNAs are derived largely from centromere-enriched retroelements, including a novel SINE. (biomedcentral.com)
  • Each class of small RNAs is synthesized by a distinct mechanism and each has discrete biological functions. (biomedcentral.com)
  • Another class of important small RNAs is the piRNAs. (biomedcentral.com)
  • Depletion of PSMC3 impairs the activity of the targeted cleavage mediated by small RNAs. (bvsalud.org)
  • Additional transgene mRNA engineering was investigated by encoding putative methylation sites in the 5' un-translated region (UTR) of a model protein therapeutic. (dcu.ie)
  • Earlier on they used MeDIP-Seq to show that a paternal low-protein diet creates a profile of modest (~20%) DNA methylation changes in the livers of offspring . (epigenie.com)
  • Human cells infected with SARS-CoV-2 exhibit a decrease in TRMT1 protein levels and TRMT1-catalyzed tRNA modifications, consistent with TRMT1 cleavage and inactivation by Nsp5. (elifesciences.org)
  • At the ribosome, the processed mRNA is translated to produce proteins from amino acid units. (cdc.gov)
  • In S. cerevisiae , this interaction is at least in part provided by Spp1 that directly interacts with both methylated H3K4 near DSB sites and the axis-localized protein Mer2 (Acquaviva et al. (springer.com)
  • Biochemical and bioinformatic analysis demonstrates that this interaction is performed in an RNA-independent manner and the N-terminal coiled-coil motif of PSMC3 is required. (bvsalud.org)
  • However, although C-terminal truncation mutant of BrYV P0 showed weaker interaction with its movement protein (MP) when compared to wild-type P0, wild-type and mutant PLRV P0 showed similar interaction with its MP. (bvsalud.org)
  • The study shows the usefulness of proteomics in identifying proteins that may express differences between sensitive and resistant L. tropica isolates. (who.int)
  • Here we present a multifunctional anchor, an acrylate epoxide, that enables proteins and RNAs to be equipped with anchors in a single experimental step. (plos.org)
