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: our_best_guess
The mRNA/+RNA description:
Putative spliced in vivo HSV-TK (thymidine kinase) promoter derived transcript containing CAT and FLuc genes
separated by FMDV IRES
The mRNA/+RNA sequence represented in the +DNA notation:
Warning: mRNA sequence when devoid of trailing 'A's is still not a substring of the plasmid sequence. Is it because an intron is spliced out? Stay calm then. :-)
Credibility of mRNA sequence: reverse_engineered_sequence_and_should_match_experiment_except_both_UTRs
The name of the promoter used to express this mRNA: HSV-TK
Description of the plasmid (facultative for promoter-less plasmid records): Incomplete pBIC plasmid containing CAT and FLuc genes separated by FMDV IRES under the control of T7 and
thymidine kinase promoters
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: FMDV
The description of the protein encoded in this ORF: firefly luciferase
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): 1230-2882
Remarks:
The +1 transcription site is not exactly known to IRESite curator so the 5'-UTR might be slightly wrong. It
seems transcription should terminate after the poly(A) signal from SV40 early region after removal of the SV40
small T antigen intron.
The sequence of the plasmid is not complete. The IRES sequence has been determined by E. Martinez-Salas while
the regions around HSV-TK promoter and intercistronic region were sequenced by IRESite (bp 2227-2802 and
3238-3961). Plasmid DNA was obtained from BCCM database.
