23-nt sequence binds CasRx to cleave WNV genome; modifiable target 2
gRNAs (guide RNAs) are relatively small RNA molecules that play a crucial role in gene editing and RNA-targeting technologies. They are typically expressed under the control of a promoter, often polymerase III, which is ideal given the high complexity of the gRNA's secondary structure. These gRNAs are composed of two main components:
The scaffold or direct repeat region
The spacer: This is a 23-nucleotide sequence that is complementary to the target RNA, guiding CasRx to the specific RNA region for cleavage. In this case, the target is a region within the West Nile Virus (WNV) genome. The spacer sequence was selected using an algorithm designed to optimize its binding and cutting efficiency, ensuring that the CasRx-gRNA complex can cleave the target RNA with high specificity and effectiveness.
By integrating both the scaffold and spacer, researchers can achieve precise RNA cleavage. This is the second spacer sequence.
