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:
hopefully_full-length_mRNA

The mRNA/+RNA description:

Putative in vivo transcript from SV40 promoter with the chimeric intron spliced out and containing
renilla_luciferase - hairpin_from_multiple_cloning_site - Kv1.4 IRES 1.2kb - firefly_luciferase and is
terminated after the late SV40 polyA signal. An FLuc-fusion protein should be translated from the second
cistron (4 aminoacids added extra).

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_both_UTRs

The name of the plasmid:
pRSTF-Kv1.4_1.2 The name of the promoter used to express this mRNA:
SV40

The in vivo produced transcripts are heterogeneous (due to any of promoter?/splicing?/cleavage?/breakage?):

yes

The in vivo produced heterogeneous transcripts occur due to alternative splicing:

yes

A promoter reported in cDNA corresponding to IRES sequence:

no

Summary of possible issues when IRES cDNA is experimentally transcribed in vivo:
