Patent number: 12071639Abstract: A polynucleotide encoding a ThermoCas9 protein from Geobacillus thermodenitrificans and a constitutive promoter are used to engineer eukaryotic cells, e.g. fungi, yeast or algae, so that the ThermoCas9 endonuclease is integrated and expressed from the genome of the cell. Then, a second expression plasmid is used to transfect these ThermoCas9 expressing cells, the second plasmid containing an inducible promoter and a polynucleotide encoding a guide RNA. The guide RNA combines with the ThermoCas9 to provide the targeted endonuclease activity to cleave the cell DNA at a desired locus or gene of interest. A repair-oligo is also provided to the cell whereby following DNA cleavage, homologous recombination takes place in the cell with the repair-oligo so that either a deletion or substitution of nucleotides in the locus or gene of interest is achieved. Expression vectors and methods of using the vectors to achieve ThermoCas9 mediated gene editing are described whereby higher temperatures, e.g. greater than 30° C.Type: GrantFiled: December 14, 2017Date of Patent: August 27, 2024Assignees: Wageningen Universiteit, Stichting Voor De Technische WetenschappenInventors: John Van Der Oost, Richard Van Kranenburg, Elleke Fenna Bosma, Ioannis Mougiakos, Prarthana Mohanraju
