IRESite record type: plasmid_with_promoter_and_putative_IRES_translationally_characterized
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 bicistronic transcript derived from SV40 promoter based pRHRVF plasmid.
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_maybe_except_3UTR
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): 1766-3418
Remarks:
The sequence of this plasmid was provided by K. Spriggs. Following is the alignment to the complete genome
sequence as determined originally by Skern et al. (1985). It is unclear when the mutations were acquired
and whether they are authentic at all. Definitely, the sequence of this plasmid differs from the similarly
named plasmid pR-HRV-F (IRESite_Id:228 and IRESite_Id:232 -- both records are based on the same plasmid
sequence, just SV40 and T7-based transcripts). This plasmid sequence from K. Spriggs lacks some regions
present in pR-HRV-F.
The pR-HRV-F plasmid contains the in-frame AUG codon which is found in HRV genome in position 449 whereas
the polyprotein AUG is located at position 611 so in theory the polyprotein produced could be much larger.
In contrast, this pRHRVF construct has some single nucleotide insertion since the AUG449 so there appears
UAG STOP codon (if this is not a mistake in the sequence we have received) which interrupts that reading
frame (uORF size 54bp in total) overlapping the IRES. BTW, there are several uORFs in HRV 5'-UTR anyway.
It is not clear whether this could make any difference in experiments (probably not).

Probably more important is the difference between both plasmids just in front of the initiator AUG (so at
the IRES 3'-end boundary):
