dCas9-Long Linker (Gly-Gly-Ser-Gly)x3-Bxb1 gp35
In this part, we fuse dCas9(BBa_K1797006) and catalytic domain of Bxb1 gp35(BBa_K907000) with a long linker(BBa_K243006). Bxb1 gp35 is a site-specific recombinase. Due to its specific recognition site, the use of recombinase is limited. To solve this problem, we fuse its catalytic domain with dCas9. Then where the Bxb1 gp35 is going to function is decided by gRNA.
Bxb1 gp35 is a serine recombinase, which functions through a tetramer(Fig.1). That means when we use dcas9-bxb1 gp35 fusion protein, we need to design four sgRNAs each time, which significantly increases the specificity.
