WebCircular RNAs are produced by pre-mRNA back-splicing of exons, which results in the exclusion of a circular RNA molecule with a 3ʹ,5ʹ‑phosphodiester bond at the junction site. 36 Circular RNAs can modulate gene expression through modulation of transcription, protein binding, sponging of miRNAs, and protein translation. 17,37,38 In this ...

Frontiers Back-Splicing Transcript Isoforms (Circular RNAs) …

WebNational Center for Biotechnology Information RNA splicing is a process in molecular biology where a newly-made precursor messenger RNA (pre-mRNA) transcript is transformed into a mature messenger RNA (mRNA). It works by removing all the introns (non-coding regions of RNA) and splicing back together exons (coding regions). For nuclear … See more Several methods of RNA splicing occur in nature; the type of splicing depends on the structure of the spliced intron and the catalysts required for splicing to occur. Spliceosomal complex Introns See more Spliceosomal splicing and self-splicing involve a two-step biochemical process. Both steps involve transesterification reactions that occur … See more The process of splicing is linked with HIV integration, as HIV-1 targets highly spliced genes. See more Splicing events can be experimentally altered by binding steric-blocking antisense oligos, such as Morpholinos or Peptide nucleic acids to snRNP binding sites, to the … See more Splicing occurs in all the kingdoms or domains of life, however, the extent and types of splicing can be very different between the major divisions. Eukaryotes splice many protein-coding messenger RNAs and some non-coding RNAs. Prokaryotes, … See more In many cases, the splicing process can create a range of unique proteins by varying the exon composition of the same mRNA. This … See more DNA damage affects splicing factors by altering their post-translational modification, localization, expression and activity. … See more WebResearch interest has recently been re-ignited in the field of non-coding RNA, especially circular RNA (circRNA), a covalently closed endogenous RNA produced by a back-splicing process. 7 CircRNA has no 3-terminal cap structure and 5-terminal poly-A tail, enabling it to be free from digestion by RNA exonuclease and very stable. 8 With the ... burnout skin
