Antisense ribosomes: rRNA as a vehicle for antisense RNAs.
Although rRNA has a conserved core structure, its size varies by more than 2000 bases between eubacteria and vertebrates, mostly due to the size variation of discrete variable regions. Previous studies have shown that insertion of foreign sequences into some of these variable regions has little effect on rRNA function. These properties make rRNA a potentially very advantageous vehicle to carry ...
متن کاملModels for pairing of IS10 encoded antisense RNAs in vivo.
Antisense regulation of IS10 transposase synthesis is mediated by a small RNA molecule, RNA-OUT which is complementary to the 5' region of the IS10 transposase mRNA, RNA-IN. Pairing between the two species in vivo prevents initiation of RNA-IN translation by steric occlusion of the ribosome binding site. The goal of this work is to develop a mathematical basis for antisense repression in vivo. ...
متن کاملRetroposition as a source of antisense long non-coding RNAs with possible regulatory functions.
Long non-coding RNAs (lncRNAs) are a class of intensely studied, yet enigmatic molecules that make up a substantial portion of the human transcriptome. In this work, we link the origins and functions of some lncRNAs to retroposition, a process resulting in the creation of intronless copies (retrocopies) of the so-called parental genes. We found 35 human retrocopies transcribed in antisense and ...
متن کاملCharacterization of plastid psbT sense and antisense RNAs
The plastid psbB operon is composed of the psbB, psbT, psbH, petB and petD genes. The psbN gene is located in the intergenic region between psbT and psbH on the opposite DNA strand. Transcription of psbN is under control of sigma factor 3 (SIG3) and psbN read-through transcription produces antisense RNA to psbT mRNA. To investigate on the question of whether psbT gene expression might be regula...
متن کاملNeighboring Gene Regulation by Antisense Long Non-Coding RNAs
Antisense transcription, considered until recently as transcriptional noise, is a very common phenomenon in human and eukaryotic transcriptomes, operating in two ways based on whether the antisense RNA acts in cis or in trans. This process can generate long non-coding RNAs (lncRNAs), one of the most diverse classes of cellular transcripts, which have demonstrated multifunctional roles in fundam...
