Abstract: Disclosed herein are novel CRISPR/dCas9-based fusion proteins that facilitate the scaling up of genetic circuits, including those with non-linear response curves. The dCas9 based fusion proteins produce significantly less toxicity in comparison to previously described CRISPR/Cas9-based proteins used with logic gates. These improvements enable the generation of complex genetic circuits when both digital response curves and large amounts of dCas9 protein are needed. Also disclosed herein are methods of regulating expression of an output sequence through the introduction of novel CRISPR/dCas-9-based fusion proteins and genetic circuits into a cell.

Abstract: The invention provides a novel approach to facilitate assembly of DNA molecules. This approach utilizes RNA-guided endonucleases, capable of targeting any DNA sequence, which cleave DNA and generate DNA fragments characterized by single stranded overhangs. After annealing of complementary overhangs, DNA fragments are covalently connected, generating a single DNA molecule. In this way, the present invention combines the reliability of classic restriction-ligation techniques, removes all sequence constraints from the desired final DNA molecule, and expands the number of DNA pieces that can be assembled at once.
