NettetSpecifically, we discuss the concept of splitCas9 whereby the Cas9 holo-protein is segregated into two parts that are expressed individually and reunited in the cell by various means, including use of 1) the gRNA as a scaffold for Cas9 assembly; 2) the rapamycin-controlled FKBP/FRB system; 3) the light-regulated Magnet system; or 4) inteins. Nettet23. mar. 2024 · Zetsche et al. (2015) showed that SpCas9 can be split into two fragments (N- and C-terminal pieces) in a different way. The two fragments were fused to FK506-binding protein (FKBP) and the FKBP12–rapamycin-binding (FRB) domain, respectively.
