The mRNP remodeling mediated by UPF1 promotes rapid degradation of replication-dependent histone mRNA
Histone biogenesis is tightly controlled at multiple steps to maintain the balance between the amounts of DNA and histone protein during the cell cycle. In particular, translation and degradation of replication-dependent histone mRNAs are coordinately regulated. However, the underlying molecular mechanisms remain elusive. Here, we investigate remodeling of stem-loop binding protein (SLBP)-conta...
متن کاملReplication protein A promotes 5′→3′ end processing during homology-dependent DNA double-strand break repair
Replication protein A (RPA), the eukaryotic single-strand deoxyribonucleic acid (DNA [ss-DNA])-binding protein, is involved in DNA replication, nucleotide damage repair, mismatch repair, and DNA damage checkpoint response, but its function in DNA double-strand break (DSB) repair is poorly understood. We investigated the function of RPA in homology-dependent DSB repair using Xenopus laevis nucle...
متن کاملCharacterisation of 3' end formation of the yeast HIS3 mRNA.
The nucleotide (nt) sequence of the 3' end of the yeast HIS3 mRNA was determined by PCR amplification of the 3' end. Analysis of 28 individual clones revealed that at least 13 distinct polyadenylation sites are present. The sites of polyadenylation are extremely heterogeneous and do not show any obvious similarity other than that they occur after pyrimidine residues in most cases. Most mutants ...
متن کاملSignals sufficient for 3'-end formation of yeast mRNA.
The following three elements were previously shown to be required for 3'-end formation of mRNA in the yeast Saccharomyces cerevisiae: (i) the efficiency element TATATA or related sequences, which function by enhancing the efficiency of downstream positioning elements; (ii) the positioning element AATAAA or related sequences, which position the poly(A) site; and (iii) the actual poly(A) site, wh...
متن کاملNon-mRNA 3' end formation: how the other half lives.
The release of nascent RNA from transcribing RNA polymerase complexes is required for all further functions carried out by RNA molecules. The elements and processing machinery involved in 3' end formation therefore represent key determinants in the biogenesis and accumulation of cellular RNA. While these factors have been well-characterized for messenger RNA, recent work has elucidated analogou...
