This tight control is … WebBirth and Death of Histone mRNAs William F. Marzluff1,2,3,* and Kaitlin P. Koreski1,3 In metazoans, histone mRNAs are not polyadenylated but end in a conserved stem-loop. Stem-loop binding protein (SLBP) binds to the stem-loop and is required for all steps in histone mRNA metabolism. The genes for the five histone proteins are linked.
WebHistone mRNAs are not rapidly degraded when DNA synthesis is inhibited or at the end of S phase in cells expressing this mutant SLBP. Replication-dependent histone mRNAs have very short 3' untranslated regions, with the stem-loop located 30 to 70 nucleotides downstream of the translation termination codon. We show here that the stability of ... Webin HU-mediated repression of histone mRNAs (Fig. 2B), we conclude that Rad53p plays an important role in DDC/DRC-mediated regulation of histone mRNAs. Histone mRNAs are degraded by canonical 50 to 3 0and 3 to 50 pathways Degradation of mRNA occurs by two general pathways, in 30 to 5 0direction or in 5 to 3 direction (Fig. 3A)(19). Both
