http://rna.whu.edu.cn/gissd/ Webthus represents a substantial rearrangement of canonical group II intron primary structure (D1-D2-D3-D4-D5-D6). Due to its similarities to group II ribozymes and the characteristic altered domain order, we recommend this collection of large noncoding RNAs be designated as the circularly permuted (CP) group II RNA class. ll OPEN ACCESS

Group II intron as cold sensor for self-preservation ... WebDec 1, 2024 · In this protocol, we used the permuted T4 thymidylate synthase (td) group I catalytic intron for the RNA circularization ( Fig. 1 B). The precursor RNA, which contains the Rluc ORF and two flanking split self-splicing introns in reverse order, is in vitro transcribed using T7 RNA polymerase.
Web2. Group I intron self-splicing and the permuted intron-ex on (PIE) method Group I intron self-splicing RNA from the ciliate Tetrahymena was the first discovered ribozyme (Cech et al., 1981). The group I intron sequence has been widely detected in eukaryotes (Cech et al., 1981), prokaryotes (Xu et al., 1990) and some bacteriophages
WebEspecially, group I intron-based trans-splicing ribozyme has unique property to use as a gene therapeutic agent. It can destroy and simultaneously repair (and/or reprogram) target RNAs to yield the desired therapeutic RNAs, maintaining endogenous spatial and temporal gene regulation of target RNAs. WebDec 1, 2024 · Group II introns constitute a ribozymatic self-splicing system with a mechanism similar to that of both group I introns and pre-mRNA introns. Mikheeva et al. (1997) demonstrated that a PIE construct capable of generating a human circRNA sequence in vitro could be made using a permuted group II intron from the yeast mitochondrial …
