IRESite record type: plasmid_with_promoter_and_putative_IRES_without_translational_characterization
The shape of the nucleic acid molecule translated: linear
The quality of the mRNA/+RNA sequence: hopefully_full-length_mRNA
The mRNA/+RNA description:
In vitro T7 run-off transcript produced from bicistronic plasmid pDC-EMCV which encodes neomycin
phosphotransferase and truncated version of the beta-galactosidase (linearized at the Ssp1 site at position
3744 within pDC-EMCV; see 1384.gb below) as the first and the second cistron respectively and the EMCV-R IRES
(nt from -575 to nt -9 of the original sequence) inserted between reporters.
The mRNA/+RNA sequence represented in the +DNA notation:
Credibility of mRNA sequence: end-to-end_sequence_reverse_engineered_and_should_match_experiment
The name of the promoter used to express this mRNA: T7
Aliases of the plasmid name:
Alias: pDC-EMCV
Description of the plasmid (facultative for promoter-less plasmid records): Plasmid containing EMCV IRES (nt from -575 to -9 of the original sequence; GI:396509) inserted between
neomycin phosphotransferase and beta-galactosidase reporter genes.
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: EMCV-R
The description of the protein encoded in this ORF: beta-galactosidase
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: not tested
The ORF absolute position (the base range includes START and STOP codons or their equivalents): 1628-2863
Remarks:
The plasmid was used as the positive control for experiments in article Characterization of two distinct RNA
domains that regulate translation of the Drosophila gypsy retroelement (Ronfort et al., 2004; PMID: 14970395).
