The name of the promoter used to express this mRNA: T7
Aliases of the plasmid name:
Alias: pXLJ0
Description of the plasmid (facultative for promoter-less plasmid records): pXLJCon is derived from pGEM-2 (Promega) backbone (GI: 58197). It contains T7 and SP6 promoter sites and is
typically used in in vitro transcription/translation assays. Bicistronic RNA, which contains B2 and NS
cistrons (GI:214094, GI:21693177), is transcribed by T7 polymerase after vector linearization by EcoRI.
The in vivo produced transcripts are heterogeneous (due to any of promoter?/splicing?/cleavage?/breakage?): not tested
The in vivo produced heterogeneous transcripts occur due to alternative splicing: not tested

Plasmid sequence verified (partially/completely) by IRESite (more details in Remarks): part of the yet unknown plasmid sequence determined by IRESite curators
A promoter reported in cDNA corresponding to IRES sequence: not tested
The total number of notable open-reading frames (ORFs): 2
Notable Open-Reading Frames (ORFs; protein coding regions) in the mRNA/+RNA sequence:
The description of the protein encoded in this ORF: Truncated form of influenza NS1 protein which is N-terminally fused with 3 amino acids
The translational frameshift (ribosome slippage) involved: 0
The ribosome read-through involved: no
The alternative forms of this protein occur by the alternative initiation of translation: no
The ORF absolute position (the base range includes START and STOP codons or their equivalents): 1407-2087
Remarks:
IRESite notes about verification of plasmid sequence:
Plasmid DNA was digested by EcoRI/SalI giving fragments 4202/699 bp. Amplification with T7 and NS gene
specific primers (T7, ATACGACTCACTATAGGG,position within plasmid sequence:2785, NS_revseq,
CTGCAACTCGTTTGCGGAC, position within plasmid sequence:4263) gave one band of expected size. The partial
sequence of the vector and the partial sequence encoding bicistronic RNA was determined by sequencing (regions
2050-4584 and 4830-350 of plasmid sequence respectively). The rest of the sequence presented here was
reverse engineered with the help of authors description and Genbank entries (GI:58197 and GI:21693177).
There is one mutation detected in the vector backbone. More detailed data are annotated in the GenBank
formatted plasmid sequence file provided on this page above.
