Saucas9 rna editing
WebbSauCas9 functions as a dual DNA/RNA targeting nuclease that can be employed in cells to regulate genes on both the transcriptional and translation level. Importantly, SauCas9 RNA-scission depends only on an sgRNA and does not need a PAMmer, thereby simplifying outstanding issues in delivery. WebbSauCas9 mutant (SauCas9KKH) that has reduced PAM con-straints (N 3RRT) has been developed, though this increase in targetingrangeoftencomesatthecostofreducedon …
