| Further information: | The mouse caspase-1 coding sequence (p30ICE-C285S) contains point mutations that convert the Cys in the active site of the conserved QACRG sequence to Ser and create an additional NheI site. The Cys conversion is described as C285S, according to the numbering of the codons in the human caspase-1 coding sequence, although the mutated mouse serine is located on position 284. 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 wild-type mouse mCASP-1cDNA corresponds with the Genbank accession number NM_009807.2. Other name of the plasmid is pLT10T3p20p10Cys/Ser ICE. |
