IRESite record type: negative_control_plasmid_with_promoter_and_without_putative_IRES
The shape of the nucleic acid molecule translated: linear
The quality of the mRNA/+RNA sequence: our_best_guess
The mRNA/+RNA description:
Putative in vivo spliced transcript derived from CMV IE promoter and terminated at the SV40 late poly(A)
signal containing Renilla and Firefly luciferases.
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: end-to-end_sequence_reverse_engineered_and_should_match_experiment
The name of the promoter used to express this mRNA: CMV_IE
The in vivo produced transcripts are heterogeneous (due to any of promoter?/splicing?/cleavage?/breakage?): no (not convincing)
The in vivo produced heterogeneous transcripts occur due to alternative splicing: no (not convincing)
Summary of possible issues when IRES cDNA is experimentally transcribed in vivo:
Summary of experiments studying integrity of the in vivo transcripts in a particular host:
Integrity (uniformity) of mRNA tested using Northern-blot: not_tested
Integrity (uniformity) of mRNA tested using RNase protection: not_tested
Integrity (uniformity) of mRNA tested using 5'-RACE: not_tested
Integrity (uniformity) of mRNA tested using primer extension : not_tested
Integrity (uniformity) of mRNA tested using RT-PCR: unclear_result
Integrity (uniformity) of mRNA tested using real-time quantitative polymerase chain reaction (rtqPCR): not_tested
Integrity (uniformity) of mRNA tested using RNAi: not_tested
Integrity (uniformity) of mRNA tested using S1 nuclease mapping: not_tested
Cryptic promoter presence was confirmed by expression from a promoter-less plasmid: no_promoter_confirmed
Cryptic promoter presence was confirmed in an experimental setup involving inducible promoter: not_tested
Integrity (uniformity) of mRNA molecules or possible promoter presence expressed in vivo was tested using another method, please specify in Remarks: not_tested
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): 1267-2919
Remarks:
Integrity of the in vivo transcripts was studied by RT-PCR, derivative of this plasmid containing 5'-UTR of
Laminin B1 and qRT-PCR. Figure 4C shows and extra, faint band corresponding probably to monocistronic derivate
of this vector containg only the FLuc ORF.
