WebCRISPR/Cas systems provide bacteria and archaea with small RNA-based adaptive immunity against foreign elements such as phages and plasmids. An important step in the resistance mechanism involves the generation of small guide RNAs (crRNAs) that, in combination with Cas proteins, recognize and inhibit foreign nucleic acids in a sequence specific manner. Web3 Aug 2024 · The Csy4 construct containing two LOB1 gRNAs achieved the successful editing of LOB1-gRNA1m-eGFP and LOB1-gRNA2m-eGFP, as indicated by green fluorescence (Supplementary Fig. 7). We then used the same gRNAs used in tRNA-based multiplex genome editing for CsPDS in Csy4 constructs (Fig. 5 a). Web1 Dec 2024 · RNA-based regulation offers a promising alternative of protein-based transcriptional networks. However, designing synthetic riboregulators with desirable functionalities using arbitrary sequences remains challenging, due in part to insufficient exploration of RNA sequence-to-function landscapes.

Webicity (roughly 20% cell death) at 400 ng Csy4 plasmid concen-trations while minimal cytotoxicity was observed at 0–200 ng Csy4 plasmid concentrations. Thus, we used 100–200 ng of the Csy4 plasmid in subsequent experiments (except where otherwise noted), although this reduced the number of Csy4-positive cells after transfection. WebThe endoribonuclease activity and 3' end-stabilizing properties of Csy4 are particularly suited for this task. Coexpression of Csy4 and the circRNA switch allows for the removal of downstream competitive splice sites and stabilization of the 5' cleavage product. This subsequently results in back-splicing of the 5' cleavage product into a ...
