Summary
Circular RNAs (circRNAs) are abundant, stable molecules with a unique looped structure. This review explores their detection, formation, and potential roles, especially in brain tissues.
Area of Science:
- Molecular Biology
- Genomics
- Neuroscience
Background:
- Circular RNAs (circRNAs) possess a unique covalently closed loop structure.
- Recent advances in RNA sequencing and bioinformatics have identified numerous circRNAs.
- Many circRNAs are abundant, stable, and evolutionarily conserved, yet their functions are largely unknown.
Purpose of the Study:
- To review recent progress in the detection and biogenesis of circRNAs.
- To discuss the potential functions of circRNAs, with a focus on neuronal tissues.
- To highlight the significance of circRNAs in brain development and synaptic plasticity.
Main Methods:
- Deep RNA sequencing (RNA-seq) for circRNA detection.
- Bioinformatic analyses for genome-wide circRNA identification.
- Literature review of studies on circRNA biogenesis and function.
Main Results:
- A large number of circRNAs have been identified across various species.
- CircRNAs are frequently enriched in neuronal tissues and linked to neuronal gene functions.
- Expression patterns of circRNAs are modulated by neuronal development and synaptic plasticity.
Conclusions:
- CircRNAs represent a significant class of non-coding RNAs with emerging roles.
- Their specific enrichment and regulation in brain tissues suggest crucial functions in neuronal biology.
- Further research is needed to fully elucidate the functional significance of circRNAs in the central nervous system.

Ribosomal RNA Synthesis
15.1K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

RNA Editing
10.1K
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

Bacterial RNA Polymerase
33.5K
Unlike eukaryotes, bacteria use a single RNA Polymerase (RNAP) to transcribe all genes. The different subunits of bacterial RNAPhave distinct functions. The multisubunit structure of the bacterial RNAP helps the enzyme to maintain catalytic function, facilitate assembly, interact with DNA and RNA, and self-regulate its activity.
In most genes, the transcription site is a single base present upstream of the coding sequence. Though RNAP is a catalytically efficient enzyme, it does not recognize...

Types of RNA
73.7K
Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

lncRNA - Long Non-coding RNAs
10.1K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Ribozymes
13.7K
The term ribozyme is used for RNA that can act as an enzyme. Ribozymes are mainly found in selected viruses, bacteria, plant organelles, and lower eukaryotes. Ribozymes were first discovered in 1982 when Tom Cech’s laboratory observed Group I introns acting as enzymes. This was shortly followed by the discovery of another ribozyme, Ribonulcease P, by Sid Altman’s laboratory. Both Cech and Altman received the Nobel Prize in chemistry in 1989 for their work on ribozymes.
