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: end-to-end_full-length_mRNA
The mRNA/+RNA description:
mRNA produced by bicistronic plasmid pRG-HCV1 which comprises DsRED2 and EGFP genes as the first and the
second cistron, respectively. The full-length 5'-UTR of HCV genomic RNA together with the first 45 nt of a
viral polyprotein gene was inserted in frame into the intercistronic region of the reporter pRG vector, thus
making the N-terminal fusion of the first 15 amino acids residues from the HCV polyprotein with the EGFP
protein. The authentic initiation 342AUG codon of HCV was substituted for 342UUG.
The sequence ends at its 3'-end right after the poly(A) signal from SV40 mRNA and thus the 3'-UTR might be
slightly wrong.

Credibility of mRNA sequence: end-to-end_sequence_completely_same_as_in_the_experiment
The name of the promoter used to express this mRNA: CMV_IE
Description of the plasmid (facultative for promoter-less plasmid records): Plasmid containing the full-length 5'-UTR of HCV genomic RNA together with the first 45 nt of a viral
polyprotein gene inserted between DsRED2 and EGFP reporter genes. The authentic initiation 342ATG codon of HCV
was substituted for 342TTG.

The IRES absolute position (the range includes START and STOP codons or their equivalents): 762-1146
How IRES boundaries were determined: experimentally_determined
5'-end of IRES relative to last base of the STOP codon of the upstream ORF: 36
3'-end of IRES relative to last base of the STOP codon of the upstream ORF: 420
5'-end of IRES relative to first base of the START codon of the downstream ORF: -404
3'-end of IRES relative to first base of the START codon of the downstream ORF: -20

Remarks:
HCV_type_1a_A/UUG IRES represents the full-length 5'-UTR of HCV RNA (type 1a) and the first 15 codons of viral
polyprotein. The authentic initiation codon of HCV polyprotein was mutated to UUG.
