IRESite: The database of experimentally verified IRES structures

The nucleic acid data:

IRESite Id: `336`	Version: `1`
Originaly submitted by: Martin Mokrejš
Reviewed by: Martin Mokrejš	Last change: `2008-02-12 22:23:35`

IRESite record type:

plasmid_with_promoter_and_putative_IRES_without_translational_characterization

The shape of the nucleic acid molecule translated:
linear The quality of the mRNA/+RNA sequence:
only_IRES_fragment

The mRNA/+RNA description:

In vitro T7 run-off transcript used for structure probing experiments of FMDV IRES domain 3 (transcription
runs off at cleaved SmaI site, FMDV IRES domain 3 is between EcoRI and SmaI sites). The GUAA motif
(generalized as GNRA) mutated to GUAG. Please note than an RNA molecule was studied and not its DNA copy.

Rendering structure of FMDV IRES in an artificial transcript 181 nt long with energy of -20.90 kcal/mol as calculated by RNAeval using VARNA Java applet with some IRESite improvements (see VARNA modified by IRESite). Hold left mouse button to move structure parts, hold right mouse button to move whole structure, use mouse wheel to zoom. Right mouse-click opens a menu to export into JPG/SVG and many other options.

You need a Java-enabled browser so that modified varsion of VARNA could be started. See http://www.iresite.org/VARNA/ for more details.
