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. WebSep 13, 2024 · In this study, the Csy4 nuclease was used to release the gRNA from CCAC (Fig. 3 A).
