Structural determinants of Sleeping Beauty transposase activity
Transposases are important tools in genome engineering, and there is considerable interest in engineering more efficient ones. Here, we seek to understand the factors determining their activity using the Sleeping Beauty transposase. Recent work suggests that protein coevolutionary information can be used to classify groups of physically connected, coevolving residues into elements called "secto...
متن کاملHelper-Independent Sleeping Beauty transposon-transposase vectors for efficient nonviral gene delivery and persistent gene expression in vivo.
Transposon-based vectors represent promising new tools for chromosomal transgene insertion and establishment of persistent gene expression in vivo. Here, we report the development of helper-independent transposon-transposase (HITT) vectors, which contain on single plasmids (i) a Sleeping Beauty (SB) transposon containing the transgene and (ii) a SB transposase expression cassette. To obtain an ...
متن کاملA Broad Range of Dose Optima Achieve High-level, Long-term Gene Expression After Hydrodynamic Delivery of Sleeping Beauty Transposons Using Hyperactive SB100x Transposase
The Sleeping Beauty (SB) transposon system has been shown to enable long-term gene expression by integrating new sequences into host cell chromosomes. We found that the recently reported SB100x hyperactive transposase conferred a surprisingly high level of long-term expression after hydrodynamic delivery of luciferase-encoding reporter transposons in the mouse. We conducted dose-ranging studies...
متن کاملTranscriptionally regulated and nontoxic delivery of the hyperactive Sleeping Beauty Transposase
The Sleeping Beauty (SB) transposase and, in particular, its hyperactive variant SB100X raises increasing interest for gene therapy application, including genome modification and, more recently, induced pluripotent stem cells (iPS) reprogramming. The documented cytotoxicity of the transposase, when constitutively expressed by an integrating retroviral vector (iRV), has been circumvented by the ...
متن کاملConditional gene expression in the mouse using a Sleeping Beauty gene-trap transposon
BACKGROUND Insertional mutagenesis techniques with transposable elements have been popular among geneticists studying model organisms from E. coli to Drosophila and, more recently, the mouse. One such element is the Sleeping Beauty (SB) transposon that has been shown in several studies to be an effective insertional mutagen in the mouse germline. SB transposon vector studies have employed diffe...
