Circrna formation mechanism
WebFeb 3, 2024 · The mechanism underlying circRNA biogenesis, particularly the process regulating circRNA formation, remains largely unknown. Notably, relevant studies concerning CRC may provide insight into the molecular mechanism of circRNA dysregulation (Fig. 4 ). Circular RNA (or circRNA) is a type of single-stranded RNA which, unlike linear RNA, forms a covalently closed continuous loop. In circular RNA, the 3' and 5' ends normally present in an RNA molecule have been joined together. This feature confers numerous properties to circular RNA, many of which have only recently been identified. Many types of circular RNA arise from otherwise protein-coding genes. Some circular RNA has …

WebMay 26, 2024 · Circular RNAs (circRNAs) are formed in all domains of life and via different mechanisms. There has been an explosion in the number of circRNA papers in recent years; however, as a relatively young ... WebApr 15, 2024 · The formation modes of circRNA include intronic complementary sequence (ICS) pair-driven cyclization, RNA binding protein (RBP)-driven cyclization and lariat-driven cyclization ( 17 ). First of all, ICS of pre-mRNA can make the distal intron splicing sites closer in space to promote reverse splicing ( Figures 2A, B) ( 18 ).
WebMar 10, 2024 · A further mechanism of circRNA biogenesis, discovered in S. pombe, implies the formation of a lariat exon-containing precursor, whose internal splicing causes the removal of the intronic sequence and the circularization of the exon .
