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).
WebGeneration of a similar 3' end by RNase P-mediated cleavage was unable to rescue transgene expression independent of Csy4. These results support the idea that the selective generation of the Csy4/hairpin complex resulting from cleavage of target mRNA might serve as a functional poly(A)/poly(A) binding protein (PABP) surrogate, stabilizing the ... c and c harley davidson in chariton iaWebJan 5, 2024 · A more sophisticated approach is to express many gRNAs from a single synthetic gene whose transcript could be processed precisely by RNases.
