CircRNA Overview

Circular RNA (CircRNA) is a type of non-coding RNA molecule without a 5' cap and a 3' poly (A) tail, forming a cyclic structure by a covalent bond. It is mainly located in the cytoplasm or stored in exosomes. Not affected by exonuclease, it is much stably expressed and hardly degraded. CircRNA is mostly formed by exon cyclization, some CircRNA lasso structures are formed by intron cyclization. According to the source, CircRNA can be roughly divided into 4 categories: ECircRNA with only exons, ElcircRNA with a combination of introns and exons, lasso CircRNA composed of introns, and CircRNA formed by intergenomic cyclization. It is currently a hotspot molecule in life science and medicine research.

Recent studies have shown that CircRNA is abundant in microRNA (miRNA) binding sites. It functions as miRNA sponge intracellularly, thereby eliminating the inhibition of miRNA on its target gene and raising the expression level of the target gene, which is called competitive endogenous RNA (ceRNA) mechanism. CircRNA plays an important role in regulating diseases through interactions with disease-associated miRNA.

CircRNA has obvious advantages as a biomarker for novel clinical diseases, and is of great research value due to its tissue specificity, disease specificity, timing specificity, and high stability.

Biological functions of CircRNA

CircRNA plays an essential biological role. Endonuclearly, it mainly affects the transcription of its parent gene and regulates the splicing of its linear homologous transcripts. Extranuclearly, it not only acts as a miRNA sponge, but also functions via binding proteins. Recent research has shown that CircRNA can be translated to functional polypeptides/proteins.

CircRNA functions as a miRNA spongy adsorbent
CircRNA contains abundant miRNA binding sites. Some CircRNA acts on MiRNA through selective sponges to prevent interactions at the 3' non-translated region, affect its level and/or activity, thereby affecting the expression of miRNA target genes.
Interaction between CircRNA and RNA-binding protein (RBP)
The CircRNA-protein binding is bidirectional. It may affects protein expression and function, and also regulates CircRNA synthesis and degradation.
CircRNA regulates gene expression
Different CircRNAs have different ways of regulating parent gene expression: Endonuclear CircRNA interferes with transcription or promotes selective splicing, extranuclear CircRNA interacts with RNA polymerase II and regulates transcription, or ElCircRNA interacts with snurposome and binds to RNA polymerase II.
CircRNA coding function (translating proteins or polypeptides)
CircRNA translation can be initiated through endogenous mechanisms in non-cap-dependent manners, such as the presence of internal ribosome entry sites (IRES) or N6-methyladenosine (M6A).
