RIBONUCLEOPROTEIN PARTICLES CONTAINING mRNA and pre-mRNA
Acta Endocrinologica, 1973ABSTRACT This paper is a review of the data concerning the nature, structural organization, properties and biological significance of the particles, containing mRNA and pre-mRNA (precursor of mRNA), i. e., (1) nuclear pre-mRNA-containing particles (2) free cytoplasmic mRNP (ribonucleoproteins), or informosomes (3) polysome-bound mRNP.

Nuclear RNA-binding proteins can record pre-mRNA processing events in the structure of messenger ribonucleoprotein particles (mRNPs). During initial rounds of translation, the mature mRNP structure is established and is monitored by mRNA surveillance systems. Competition for the cap structure links translation and subsequent mRNA degradation, which may

Pre-mRNA processing and mRNA nuclear export
Current Opinion in Cell Biology, 1989The primary transcript of a prokaryotic gene is translated immediately following or during synthesis, whereas in eukaryotes, messenger RNA (mRNA) precursors (premRNAs) are synthesized in the nucleus and are then structurally altered and relocated to the cytoplasm before translation (Fig. 1).

Uridine addition at the 3' end of RNAs (i.e., uridylation) emerges as a critical posttranscriptional modification promoting RNA degradation. Uridylation has been notably linked to the degradation of small RNAs, correlated with the 5' shortening of RISC-cleaved transcripts and the degradation of mRNAs.

Hybridization of mRNA and pre-mRNA with the sequences forming double-stranded structures in pre-mRNA
Molecular Biology Reports, 1973About 25% of the double-stranded sequences isolated from pre-mRNA are able to hybridize, after melting, with either mRNA or non-melted pre-mRNA. The retention of one branch of pre-mRNA hairpin in mRNA was suggested. It was also found that in addition to the hairpin-like structures comprising about 3% of the total sequences another 15% of the pre-mRNA ...

CYP3A5 mRNA Degradation by Nonsense-Mediated mRNA Decay
Molecular Pharmacology, 2005The total CYP3A5 mRNA level is significantly greater in carriers of the CYP3A5*1 allele than in CYP3A5*3 homozygotes. Most of the CYP3A5*3 mRNA includes an intronic sequence (exon 3B) containing premature termination codons (PTCs) between exons 3 and 4.

SummaryAlthough plasmid‐borne and chromosomal toxin–antitoxin (TA) operons have been known for some time, the recent identification of mRNA as the target of at least two different classes of toxins has led to a dramatic renewal of interest in these systems as mediators of stress responses.

The cytoskeleton and mRNA localization
Current Opinion in Cell Biology, 1992The localization of mRNA appears to facilitate protein sorting, so that proteins are synthesized in specific cellular regions. The spatial information on the mRNA may be transduced by proteins that recognize specific localizing sequences on the 3' end and then chaperone the mRNA, presumably along filaments, to its destination. Additional sequences such
