Homogenous Time Resolved Fluorescence Assay to Identify Modulators of Cap-Dependent Translation Initiation
Bibliographic record
Abstract
Eukaryotic initiation factor (eIF) 4F plays a key role in recruiting 40S ribosomes and associated factors to mRNA templates during translation initiation. The function of this heterotrimeric complex is to deliver an RNA helicase to the 5 cap proximal region of mRNAs in preparation for ribosome binding. To study the interaction between subunits of this complex, as well as identify small molecules that could interfere with their association, we developed a time resolved fluorescence assay that allows monitoring of interactions between two subunits of eIF4F. We have performed a small molecule chemical screen of > 73,000 compounds using this assay. Keywords: Time-resolved fluorescent resonance energy transfer, FRET signal, Isothermal Titration Calorimetry, Recombinant Proteins, Eukaryotic initiation factor 4E binding protein

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.
