crRNA is crucial for the CRISPR Cas system. It is the short sequence that combines with Cas12a protein and forms a functional complex. Once crRNA binds with Cas12a protein, the complex capable to target and cleave targeted double-stranded DNA sequence (cis cleavage activity) and the cleavage of double-stranded DNA activates the cleavage of non-specific ssDNA (trans cleavage activity). In our project, we use crRNA for detecting a part sequence of vp72 membrane protein of African swine fever virus (ASFV).
 
  
When crRNA 1 binds with Cas12a protein, the protein may carry out cis-trans cleavage activity once it recognizes its target. By the way, though crRNA 1 is derived from ASFV, there is no possibility for virulence. The sequence of crRNA 1 is derived from p72 which is the capsid of ASFV. Therefore, the sequence of crRNA 1 is too short to be a functional protein. Thus, there is probably no risk for the spread out of ASFV from our project. Therefore, the design of this gene expression was reported in the check-in form and got approved.

DNA template of crRNA 1 for LbCas12a


This part encode the crRNA-1 that mediates Cas12a protein to recognize target sequences. Once crRNA binds with Cas12a protein, the complex capable to target and cleave targeted double-stranded DNA sequence (cis cleavage activity). The cleavage of double-stranded DNA activates the ability of Cas12a protein to cleave non-specific ssDNA (trans cleavage activity). In our project, crRNA-1 is designed to detect specific sequence of vp72 gene in African swine fever virus (ASFV).

Of note, crRNA-1 only contains 20 nucleotide sequences from vp72 gene of ASFV, which shows no potential of protein coding. Our design had been reported to iGEM and got approved.
