WebAn active human histone pre-mRNA 3'-end processing machinery has been reconstituted, using 13 proteins and 2 RNAs (U7 ring, HCC, SLBP, FLASH, U7 snRNA, H2a* histone pre-mRNA). The structure of the active machinery has been determined by cryo-EM. The overall structure has the shape of an amphora. The HDE-U7 duplex is surrounded by symplekin … WebIn metazoans, histone mRNAs are not polyadenylated but end in a conserved stem-loop. Stem-loop binding protein (SLBP) binds to the …

WebThe expression of the replication-dependent histone mRNAs is tightly coupled with DNA replication, with significant amounts of histone mRNA present only in S phase. The concentrations of histone mRNA are regu- lated at both transcriptional and post-transcriptional steps (Sch~mperli 1986; Marzluff and Pandey 1988;

WebFeb 20, 2013 · Histone transcription is tightly regulated during the cell cycle. In some organisms like S. cerevisiae, transcription of histones can only be detected in late G1 and during DNA replication [ 55 ]. In higher eukaryotes, however, histones mRNAs can be found at all stages but increase as cells enter S-phase [ 56 ].
WebZygotic genome activation (ZGA) plays an essential role in early embryonic development. Vitrification is a common assisted reproductive technology that frequently reduces the developmental competence of embryos. However, the effect of vitrification on porcine ZGA and gene expression during ZGA remains largely unclear. Here, we found that …
