Lost Once, the Fragile X Mental Retardation Protein is Now Back onto Brain Polyribosomes
Bibliographic record
Abstract
The Fragile X Mental Retardation protein (FMRP) is an RNA-binding protein and its absence leads to the Fragile X syndrome, the most common form of inherited mental retardation. Because it has been acknowledged for a long time that FMRP is associated with polyribosomal mRNPs in all non-neuronal cellular systems studied so far, it is thought that it regulates translation in neurons also; however, its exact function remains elusive. Recently, it has been reported that, contrary to non-neuronal cells, brain FMRP is not associated with the translation machinery, but is part of repressed small RNP complexes excluded from polyribosomes.(27) To elucidate this puzzling result, Stefani et al.(17) and Khandjian et al.(32) have optimized methods to analyze brain polyribosomes and now provide definitive evidence for the association of FMRP with brain polyribosomes. In addition, the data presented in these two reports clearly indicate that FMRP's function resides at the translation control level.

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.
