putative LINE-1 ORF2 IRES linearized at XbaI site
The mRNA/+RNA sequence represented in the +DNA notation:
Credibility of mRNA sequence: end-to-end_sequence_reverse_engineered_and_should_match_experiment
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

Remarks:
In preparing for submission of this IRESite record, it was found that there are 3 PCR errors (A->G @ 1481,
C->T @ 1649, del @ 1784) and a nucleotide difference between the PCR template and the GenBank database (T->G @
1592).
Overview of the mutants shown in 7B:
mL1-ORF2-138-1-mut1
2804-2941
This tested sequence is identical to "mL1-ORF2-138-1" except for 3 single point mutations [2820(G->C),
2836(A->C), 2838(G->C)] introduced to disrupt a predicted stem-loop.
mL1-ORF2-138-1-mut2
2804-2941
This tested sequence is identical to "mL1-ORF2-138-1" except for 6 single point mutations [2812(C-G),
2815(T-G), 2820(G-C), 2833(C-G), 2836(A-C), 2838(G-C)] introduced to disrupt and then restore a predicted
stem-loop.
mL1-ORF2-138-1-mut32804-2941
This tested sequence is identical to "mL1-ORF2-138-1" except for 5 single point mutations [2810(A-T),
2820(G-C), 2836(A-C), 2838(G-C), 2840(T-A)] introduced to disrupt a predicted stem-loop and avoid introducing
a small ORF.
mL1-ORF2-138-1-mut4
2804-2941
This tested sequence is identical to "mL1-ORF2-138-1" except for 8 single point mutations [2810(A-T),
2812(C-G), 2815(T-G), 2820(G-C), 2833(C-G), 2836(A-C), 2838(G-C), 2840(T-A)] introduced to disrupt/restore a
predicted stem-loop and avoid introducing a small ORF.
