tCas9-Vp64(Prokaryotic)

The CRY2/CIBN interaction is entirely genetically encoded. The binding reverses within minutes in the dark, allowing rapid shutoff of transcription by placing samples in the dark. This fusion protein is for use in LACE(light-activated CRISPR/Cas9 effector) system, and a tCas9 fused to its N terminus. To regulate DNA transcription by blue light, the system is based on CRY2/CIBN interaction in which a light-mediated protein interaction brings together two protein (tCas9 and an activation domain VP64) . If we remove the stimulation of blue light, dark reversion of CRY2 will dissociate the interaction with CIBN and shut off transcription.

tCas9 can be tagged with transcriptional activators, and targeting these dCas9 fusion proteins to the promoter region results in robust transcription activation of downstream target genes. This tCas9-based activators is the case that tCas9 fused directly to a single transcriptional activator( VP64).
