|Further information:||The plasmid was constructed by introducing an Y726 deletion into the human LZTR1 coding sequence of pLenti-CMV-HA-LZTR1-puro.
The nucleotide sequence of the human LZTR1 coding sequence was altered for ease of synthesis but contains no codon changes other than Y726.
The plasmid contains all of the viral processing elements necessary for the production of replication-incompetent lentivirus, as well as elements to improve viral titer, transgene expression and overall vector function.
The woodchuck hepatitis virus posttranscriptional regulatory element (WPRE) promotes RNA processing events and enhances nuclear export of viral and transgene RNA, leading to increased viral titers from packaging cells and enhanced expression of the mutated LZTR1 in target cells.
The plasmid includes a Rev-response element (RRE), which further increases viral titers by enhancing the transport of unspliced viral RNA out of the nucleus.
The plasmid also contains a central polypurine tract/central termination sequence element (cPPT/CTS). During target cell infection, this element creates a central DNA flap that increases nuclear import of the viral genome, resulting in improved vector integration and more efficient transduction.
Because of the high risk for recombination, this plasmid is only available under the format of isolated plasmid DNA.
Other name of the plasmid is pLenti CMV HA-LZTR1 Y726* puro (1750).
