Abstract: The present invention relates to composition comprising a clustered, regularly interspaced, short palindromic repeats (CRISPR) system comprising i) at least one CRISPR-associated protein 13 (Cas13) or a nucleotide sequence encoding said Cas13 protein fused with at least one nuclear localization signal (NLS) fused to at least one nuclear export sequence (NES) and ii) at least one guide RNA (gRNA) or a nucleotide sequence encoding said gRNA capable of hybridizing with one or more target RNA molecules.

Abstract: The present invention relates to a method for detecting a nucleic acid construct or part thereof and/or for detecting the expression product of the nucleic acid construct or part thereof, wherein the method comprises inserting a nucleic acid construct or part thereof into an intron or a synthetic intron, wherein the nucleic acid construct comprises certain defined structures according to the present invention. The present invention also relates to the various uses of the method described herein, to the nucleic acid construct, a vector comprising said nucleic acid construct, a cell comprising said nucleic acid construct and/or said vector, and a respective kit.

Abstract: The present invention relates a vector system and a vector system for use in a method of treating a disease, each comprising a first vector and a second vector. The present invention further relates to the first vector, the second vector and a combination of the first vector and the second vector. In addition, the present invention relates to a pharmaceutical composition comprising the vector system of the invention or the combination of the invention.

Abstract: The invention provides a method for detecting a specific splice event of a gene of interest, wherein the specific splice event creates a specific splice product, which comprises an exon of interest, wherein the method comprises: (i) Inserting a split intein—heterologous polynucleotide construct into the exon of interest, wherein the split intein comprises an N-terminal splicing region upstream of the heterologous polynucleotide and a C-terminal splicing region downstream of the heterologous polynucleotide; and (ii) detecting the heterologous polynucleotide and/or the expression product of the heterologous polynucleotide. The present invention also provides the use of the split intein—heterologous polynucleotide construct, the nucleic acid encoding this construct, the vector and the host cell comprising the nucleic acid as well as a kit for detecting a specific splice event of a gene of interest.

Abstract: The present invention relates to a precursor of a molecular sensor for determining analyte concentrations and/or measuring analyte concentration changes comprising a host for an active nucleus, an NMR-modulating moiety and an interacting moiety, wherein said NMR-modulating moiety changes the resonance frequency or the chemical exchange saturation transfer (CEST) signal of the active nucleus-host complex, and wherein said interacting moiety specifically responds to an environmental parameter, to an analyte or to a target molecule that binds the analyte or said interacting moiety specifically binds to a target molecule in an analyte-dependent manner. The present invention further relates to a molecular sensor comprising an active nucleus and said precursor. The present invention further relates to a molecular sensor for determining analyte concentrations and/or measuring analyte concentration changes inside a cell, wherein moiety/ies of the sensor are expressed in said cells and then assembled inside said cell.
