PIF6-CreN
Multi-Component SwitchPIF6-CreN is the PIF6-fused N-terminal Cre fragment used in the CreLite optogenetic recombinase system. In the presence of phycocyanobilin (PCB), 660 nm red light induces association with PhyB-CreC, reconstituting Cre recombinase activity for light-controlled loxP recombination in developing zebrafish embryos.
