Credibility of mRNA sequence:

end-to-end_sequence_reverse_engineered_and_should_match_experiment

The name of the plasmid:
pXLCSFV2-423.NS The name of the promoter used to express this mRNA:
T7

Description of the plasmid (facultative for promoter-less plasmid records):
pXLCSFV2-423.NS is a derivative of pXL10S. CSFV IRES corresponding to 2-423 bp of viral genomic RNA has been inserted between the two cistrons using SnaBI and EcoRI enzymes. The pXLJ0S 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

A promoter reported in cDNA corresponding to IRES sequence:

not tested

The abbreviated name of the donor gene or virus from which this IRES was excised and inserted into the plasmid:
CSFV

The origin of IRES in the plasmid:

viral

The donor organism of the IRES segment:

Classical swine fever virus Alfort/Tuebingen

Remarks:

IRESite notes about verification of plasmid sequence:
The sequence of pXLCSFV2-423.NS (pXLJ0S respectively) was derived from the pXLJCon sequence which has been
experimentally determined by IRESite curators (please see the IRESite entry 329). The sequence of pXLJ0S
differs from pXLJCon in a creation of SnaBI restriction site at position 4202 of plasmid sequence.  A mutation
in vector backbone at position 2808 is indicated in pXLCSFV2-423.NS .gb file provided by IRESite. This
mutation has been detected by sequencing of pXLJCon, thus it is not clear if it is present in pXLJ0S series as
well.
