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:
Bicistronic mRNA molecule coding for RLuc-CSFV_IRES followed by 54nt from CSFV N-pro sequence followed by KpnI
site, hairpin and CAT. It should have been better named pRLuc-CSFV+54-hpCAT.
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: Chloramphenicol acetyltransferase with N-terminal 54nt from CSFV N-pro ORF followed by KpnI site, hairpin stem
loop and followed by CAT ORF.
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): 1372-2115
The IRES absolute position (the range includes START and STOP codons or their equivalents): 999-1426
How IRES boundaries were determined: experimentally_determined
5'-end of IRES relative to last base of the STOP codon of the upstream ORF: 31
3'-end of IRES relative to last base of the STOP codon of the upstream ORF: 458
5'-end of IRES relative to first base of the START codon of the downstream ORF: -373
3'-end of IRES relative to first base of the START codon of the downstream ORF: 54
The sequence of IRES region aligned to its secondary structure (if available):
Remarks:
The first base from the KpnI site is annotated here as belonging to IRES although this is not consistent with
other records derived from same article. really only 54nts are retained from CSFV N-pro ORF.
