The present invention relates to polypeptides and more particularly to Transcription Activator-Like Effector derived proteins that allow to efficiently target and/or process nucleic acids. The present invention also concerns methods to use these proteins. The present invention also relates to vectors, compositions and kits in which RVD domains and Transcription Activator-Like Effector (TALE) proteins of the present invention are used.

Repeat variable diresidues for targeting nucleotides

The present invention is in the field of CRISPR-Cas system for genome targeting. The present invention relates to new engineered Cas9 scaffolds and uses thereof. More particularly, the present invention relates to methods for genome targeting, cell engineering and therapeutic application. The present invention also relates to vectors, compositions and kits in which the new Cas9 scaffolds of the present invention are used.

Compact scaffold of Cas9 in the type II CRISPR system

The present invention relates to a method for the generation of compact Transcription Activator-Like Effector Nucleases (TALENS) that can efficiently target and process double-stranded DNA. More specifically, the present invention concerns a method for the creation of TALENs that consist of a single TALE DNA binding domain fused to at least one catalytic domain such that the active entity is composed of a single polypeptide chain for simple and efficient vectorization and does not require dimerization to target a specific single double-stranded DNA target sequence of interest and process DNA nearby the DNA target sequence. The present invention also relates to compact TALENs, vectors, compositions and kits used to implement the method.

Method for the generation of compact tale-nucleases and uses thereof

The present invention relates to new Transcription Activator-Like Effector proteins and more particularly new Transcription Activator-Like Effector Nucleases (TALENs) that can efficiently target and process nucleic acids. The present invention also concerns methods to use these new Transcription Activator-Like Effector proteins. The present invention also relates to vectors, compositions and kits in which Transcription Activator-Like Effector proteins of the present invention are used.

Tale-protein scaffolds and uses thereof

The present invention concerns new modular base-per-base specific nucleic acid binding domains (MBBBD) derived from newly identified proteins from the bacterial endosymbiontand their use for engineering nucleic acid processing enzymes, such as specific endonucleases or transcription activators.

Modular base-specific nucleic acid binding domains from burkholderia rhizoxinica proteins

The present invention relates to a method to engineer immune cell for immunotherapy. In particular said immune cells are engineered with chimeric antigen receptors, which be activated by the combination of hypoxia and ligand extracellular binding as input signals. The invention also relates to new designed chimeric antigen receptors which are able to redirect immune cell specificity and reactivity toward a selected target exploiting the ligand-binding domain properties and the hypoxia condition. The present invention also relates to cells obtained by the present method, in particular T-cells, comprising said chimeric antigen receptors for use in cancer treatments.

Method of engineering multi-input signal sensitive T cell for immunotherapy

The present invention relates to a method for the generation of compact Transcription Activator-Like Effector Nucleases (TALENs) that can efficiently target and process double-stranded DNA. More specifically, the present invention concerns a method for the creation of TALENs that consist of a single TALE DNA binding domain fused to at least one catalytic domain such that the active entity is composed of a single polypeptide chain for simple and efficient vectorization and does not require dimerization to target a specific single double-stranded DNA target sequence of interest and process DNA nearby said DNA target sequence. The present invention also relates to compact TALENs, vectors, compositions and kits used to implement the method.
