RNAMake-ΔΔG accounts for changes in tertiary RNA assembly affinity in a blind prediction challenge.

Scatterplot compares the dependence of the observed changes in ΔΔG (compared to the median) on the RNAMake-ΔΔG model for 1536 chip piece variants (R = 0.84). Red dashed line indicates the best-fit line (slope = 0.54); cyan dotted line indicates the line of slope 1.

Problems in RNA nanotechnology solved by RNAMake

(a) ‘miniTTRs’ require two strands (green, purple between tetraloop (orange) and tetraloop-receptor (blue); (b) tethered ribosomes require two strands (green, purple) to link the small subunit (orange) to the large subunit (blue). c) ‘Locking’ a small-molecule binding aptamer (cyan; ATP molecule in pink spheres) by designing four strands (green, purple, teal, magenta) to a peripheral tertiary contact(orange, blue). d) Demonstration of RNAMake design algorithm, which builds an RNA path via the successive addition of motifs and helices from a starting base pair to the ending base pair.

M2-seq recovers helices across diverse RNA folds

M2-seq recovers the secondary structure of the P4–P6 domain of Tetrahymena ribozyme. Depicts the crystallographic secondary structure and M2-seq data (square graphs) with colored labels (on both display items) marking helices and multihelix domains automatically identified by M2-net analysis (A neural network).
