WebJun 2, 2024 · Csy4 is an RNase of the CRISPR system of Pseudomonas aeruginosa that processes the transcript of the CRISPR array to release the CRISPR-derived RNAs … WebJan 5, 2024 · A more sophisticated approach is to express many gRNAs from a single synthetic gene whose transcript could be processed precisely by RNases. For example, self-cleavable ribozyme and Csy4 RNase were engineered to produce multiple gRNAs from one RNA transcript [12, 13]. Interestingly, eukaryotic cells contain various endogenous RNA …
WebFeb 21, 2024 · This is consistent with predominant forward splicing to produce linear species in the absence of Csy4. In contrast, when circGFP-CD is coexpressed with Csy4, an RNase R resistant product was observed, representing circular RNA (Fig. 3 C, lanes 3,4; 45.1% of the undigested). These results are consistent with Csy4-activated circRNA production. WebThe cas genes are expressed as an operon and all three CRISPR arrays are transcribed and processed into small RNAs. The Csy4 protein was identified as responsible for …
