Design Notes

In order to prevent the fusion protein has steric hindrance, We use a 17aa GS linker to link the light-induced dimerization protein with a part of dCas9, which split by a rational strategy of Cas9. According to the different function and spatial position between α-helix lobe and nuclease, we split dCas9 into two parts. Rad1 includes a-helix lobe, Rad2 includes nuclease lobe. You can use this part with https://parts.igem.org/Part:BBa_K2381002

Source

The light-induced protein nMagHigh is made from the VVD protein family derived from the fungus Neurospora crassa. The Rad2 is made from the dCas9 Protein derived from the Streptococcus pyogenes.
