Circrna formation mechanism
WebAug 3, 2024 · Circular RNAs (circRNAs) are regulatory RNA molecules that are covalently closed by back-splicing, in which a downstream splice donor is joined with an upstream splice acceptor [ 1 ]. circRNAs have been reported to bind to microRNAs (the so-called “miRNA sponges”) [ 2, 3] and to act as decoys for proteins to regulate the expression … WebApr 14, 2024 · CircRNA, the latest research hotspot in the field of RNA, is a special non-coding RNA molecule, which is unable to encode proteins and bind polyribosomes.
