Phage f1 origin
|Host range:||Escherichia coli; use strains with a cI function, cIts for PL controlled expression|
|Further information:||The mouse caspase-1 coding sequence (p45ICE-2DE) contains point mutations, converting two Asp (D) amino acids of the prodomain to Glu (E) to destroy potential cleavage sites, and creating additional BalI (MscI) and KpnI restriction sites.
Transcriptional read-through from the promoters is minimized by the presence of a duplicated T7 transcription terminator and a duplicated fd transcription terminator. Read-through transcription from other plasmid promoters is minimized by the clockwise orientation of the PL and T7 promoters relative to the anticlockwise orientation of the replication origin.
Furthermore, the phasmid is provided with an antisense phage T3 promoter. It also contains the replication origin of the single-stranded DNA phage f1, so that it can be rapidly switched between the plasmid and the phage mode (ssDNA) of replication.
The nucleotide sequence of the mouse mCASP-1cDNA corresponds with the EMBL Nucleotide Sequence Database accession number BC008152.1.
Other name of the plasmid is pLT10T3PROCASP-1Asp.
