(work in progress)
== The idea ==
In the future, EteRNA players will face the challenge of creating RNA sequences that can change shape by binding other RNAs rather than reacting to ligands like FMN or Theophylline.
A well-known interaction HIV TAR-TAR*
PDB accession 1KIS.
== Parameters for candidates ==
"Natural" folding (MFE) should
- not have the hairpin features
- not have the complementary sequences bound
Constrained folding should
- have the hairpin features
- have as few free bases as possible in the portion inbetween (in an attempt to guarantee that the stems will coaxially stack, thereby nullifying risks of pseudoknot formation)
== Examples ==
=== Candidate 1 ===
