WebNov 9, 2024 · The use of Csy4 RNase-based multiplexing has been extensively reported in human cells and yeast (Tsai et al. 2014; Nissim et al. 2014). To express multiple gRNAs as a single RNA transcribed from a single promoter, each gRNA is flanked by Csy4 cleavage motifs as spacers (Čermák et al. 2024). WebMar 2, 2012 · Biochemical assays and three co-crystal structures of wild-type and mutant Csy4/RNA complexes reveal a substrate positioning and cleavage mechanism in which a histidine deprotonates the ribosyl 2'-hydroxyl pinned in place by a serine, leading to nucleophilic attack on the scissile phosphate.
