|Further information:||This bicistronic lentiviral expression vector was constructed by PCR amplifying the human MALT1 coding sequence from pCD-MK and cloning it as a NotI/BamHI fragment into the pLVX-EF1alpha-IRES-ZsGreen1 vector.
pLVX-EF1alpha-hMALT1-IRES-ZsGreen1 is a HIV-1-based, lentiviral expression vector designed to simultaneously and constitutively express hMALT1 and ZsGreen1 from a bicistronic transcript in mammalian cells.
ZsGreen1 is a human-codon-optimised variant of the reef coral Zoanthus sp. green fluorescent protein (ZsGreen) that has been engineered for brighter fluorescence. The excitation and emission maxima of native ZsGreen1 are 493 nm and 505 nm, respectively.
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 RNA, leading to increased viral titers from packaging 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.
The nucleotide sequence of the human MALT1 coding sequence corresponds with the EMBL Nucleotide Sequence Database accession number AF130356.2.
