Webbcontaining an m7G-modied cap, which is added by another m6A m methyltransferase, methyltransferase-like 14 (METTL14) [40]. e internal m6A m modication and m7G cap cooperate to regulate global RNA alterna-tive splicing, which may further inuence more biological functions in human diseases [40]. Role of m7G in cancer WebbThis paper pro- vides structural and mechanistic insights into the roles of the m7G cap and 2′-O-methylation in RIG-I evasion. We show that RIG-I accommodates the m7G base while maintaining the 5′ppp contacts and can recognize Cap-0 RNAs but not Cap-1. Author contributions: S.S.P. and J.M. designed research; S.C.D., C.W.,

Webb9 juli 2024 · The m7G cap is ubiquitous on RNAPII-transcribed RNA and has fundamental roles in eukaryotic gene expression, however its in vivo role in mammals has remained unknown. Here, we identified the m7G cap methyltransferase, RNMT, as a key mediator of T cell activation, which specifically regulates ribosome production.

Webb17 mars 2024 · The term ARCA refers to Anti-Reverse Cap Analog. In this modified cap analog, the three prime hydroxyl (3’-OH) group closer to the 7-methyl-guanosine (m7G) is replaced with a methoxy group (–OCH3) group. The anti-reverse cap analog (ARCA: 3´-O-Me-m7G(5 )ppp(5 )G) prevents that synthetic mRNAs will have the cap-0 in the reverse … WebbThis effort resulted in unprecedented mRNA synthesis that generates a unique blocked and methylated 5' terminal structure (referred later to as "cap" or "m (7)G-cap") in the … Webb10 nov. 1978 · This specificity indicates that 2'-O-methylation is the final step in the formation of the m7G (5')pppNm- cap structure.
