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:
Putative spliced bicistronic mRNA derived from pSL based plasmid with part of the 5' UTR (nt 1089 to nt 1152)
of human myelin transcription factor 2 (MYT2) mRNA cloned between chloramphenicol acetyltransferase and
firefly luciferase.
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. :-)

The relative translation efficiency in % of this IRES: 41.000
Name of IRES used as the positive control: BiP
Name of the plasmid used as the positive control. pcBIP
Name of the plasmid used as the negative control. pCAT/LUC
IRESite Id of the plasmid used as negative control. 218
The relative translation efficiency in % of the positive control: 100.000
The relative translation efficiency in % of the negative control: 25.000
The size (length) of intercistronic region in the positive control: 264
The size (length) of intercistronic region in the negative control: 76
The effect of 5'-cap analogs on translation: not tested
Rapamycin affects translation: not tested
Type of RNA subject to translation: endogenous_nuclear_RNA_Pol_II_transcript
Remarks:
The pcBIP plasmid is currently not available. It is also not clear whether the pCAT/LUC plasmid used as
negative control was the one with 76b long intercistronic region or whether the plasmid was pCAT/LUC with 17nt
long hairpin structure. However, authors mention luciferase activities in SVG and HeLa cells was same.
