The present invention relates to an adeno-associated virus (AAV), comprising an insertion of at least 6-8 amino acids between the positions corresponding to position 587 and 588 of SEQ ID NO: 1. Also envisioned are AAVs of the present invention for use as a medicament and pharmaceutical compositions comprising the AAV of the present invention. Further, the present invention relates to an in vitro use of AAV of the present invention for transduction of the nucleus of retinal cells. Also concerned is a method for screening an insertion sequence as well as a peptide obtainable by the method for screening. Also contemplated are kits comprising the AAV of the present invention.

AAV vectors

In a first aspect, the present invention relates to a mutated adeno-associated virus (AAV) capsid protein or fragment thereof wherein a substitution of a wild type non-cysteine amino acid into a cysteine is present whereby the wild type non-cysteine amino acid is exposed on the outer surface of the capsid of an AAV particle. In a further aspect, a mutated AAV particle comprising the AAV capsid protein or fragment thereof according to the present invention is provided. In addition, a nucleic acid encoding the AAV capsid protein according to the present invention is identified together with a corresponding nucleic acid vector, in particular, a plasmid or a gene string. In addition, a host cell containing the nucleic acid vector or the nucleic acid according to the present invention as well as a composition comprising at least an infectious (transducing) AAV particle containing a mutated AAV capsid protein as defined herein together with a non-infectious AAV particle containing a mutated AAV capsid protein as e.g. defined herein is disclosed. Further, a method for the modification of a mutated AAV particle is disclosed allowing a specific modification of the same including an embodiment using a reagent addressing the cysteine residues for binding reaction such as a thioether binding.

Mutated adeno-associated viral capsid proteins for chemical coupling of ligands, nanoparticles or drugs via thioether binding and production method thereof
