Abstract
The present invention provides elements for producing recombinant nucliec acid molecules and/or recombinant cells. The elements are capable of integrating desired nucleic acid material into other nucleic acid materials, specifically into the genome of a host cell. The elements are derived from or based an transposons, in particular from the Tc/Mariner superfamily. In particular the essential elements of Tc1 enabling excision and pasting of the desired nucleic acid material are provided, together with the relevant transposase activity in cis or in trans.
Claims15
A vector for providing a cell of a certain genome with additional nucleic acid material integrated in its genome, whereby said vector comprises two transposase binding sites, whereby said transposase binding sites may be the same or different and are derived from a transposon found in another genus each in close proximity to a cut site for saiid transposase, whereby said additional nucleic acid material is located between said two transposase binding sites.
A vector according to anyone of the aforegoing claims, further comprising a means for transducing a target cell.
A vector according to anyone of the aforegoing claims further comprising a nucleic acid sequence encoding transposase activity, functional for the transposase binding sites and cut sites present in said vector.
A vector according to anyone of the aforegoing claims, whereby the additional nucleic acid material encodes a protein.
A vector according to anyone of the aforegoing claims, whereby said vector is derived from a viral vector, preferably an adenoviral, retroviral, or adeno associated viral vector.
A method for providing a target cell with additional nucleic acid material integrated into its genome comprising transducing said cell with a vector according to anyone of the aforegoing claims and providing said target cell with transposase activity functional for the transposase binding sites and cut sites present on said vector.
Use of a functional transposon found in a certain genus in integrating a nucleic acid of interest into the genome of a cell of a different genus.
