Probing FinO???FinP RNA interactions by site-directed protein???RNA crosslinking and gelFRET
Bibliographic record
Abstract
The conjugative transfer of F-plasmids is repressed by a two-component system, which consists of the antisense RNA FinP and the protein FinO. FinO binds FinP, protecting it from endonucleolytic degradation and facilitating duplex formation between FinP and its complementary RNA. Here we present the results of site-specific protein-RNA cross-linking and gel-based fluorescence resonance energy transfer (gelFRET) experiments used to probe the structure of a complex of FinO bound to an RNA target consisting of a duplex with 5' and 3' single-stranded tails. The crosslinking experiments reveal that an extensive, largely positively charged surface on FinO contacts RNA. The gelFRET measurements indicate that the 5' single-stranded tail of the RNA is in closer contact with much of the protein than the distal, blunt end of the RNA duplex. These data suggest that significant conformational adjustments in the protein and/or the RNA accompany complex formation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
