| Further information: | The plasmid was constructed by two successive three-point ligations as follows: (i) the PCR amplified UNR(Δ255-270) fragment was digested with XbaI-NcoI and cloned together with the firefly luciferase coding sequence, obtained as an NcoI-HindIII fragment from pSV-Sport-Fluc, in the XbaI-HindIII linearized vector pUC19, (ii) the UNR(Δ255-270)-Fluc insert was then recovered as an XbaI fragment and cloned in the XbaI linearized pSV-Sport-Rluc. pSV-Sport-di-RF-UNR(d255-270) is a dicistronic expression vector with a deletion mutant (Δ255-270) of the internal ribosome entry site of the human upstream of N-ras (UNR) isoform 1 cloned between upstream rLUC and downstream LUCm coding sequences. The IRES can drive translation of the downstream LUCm sequence independently of the 5'-cap structure bound to the 5'-end of the mRNA molecule. Overexpression of the human heterogeneous nuclear ribonucleoprotein C1 (hnRNPC1) stimulates the activity of this UNR deletion mutant that still contains the 348-355 oligo(U) stretch involved in the binding of hnRNPC1. This observation supports the finding that the binding of hnRNPC1 to the UNR IRES at the continuous oligo(U) stretch enhances its activity. When cloning a fragment downstream from the lac promoter it may be advisable to use lacI(q) strains in order to prevent fortuitous expression of a possibly noxious polypeptide. The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT726972.1. The nucleotide sequence of the 5' UTR of the human UNR isoform 1 was obtained from Genbank (Accession number NM_001007553.1). Name mentioned in Schepens et al. (2007) is Di-pRF-UNR (Δ255-270). Other name of the plasmid is Di-UNR (delta255-270). |
