Abstract
Background: Retrotransposon LINE-1 causes dozens of genetic diseases. Results: Human MOV10 diminishes the level of LINE-1 RNA by acting at a post-transcriptional stage. Conclusion: The host protein suppresses LINE-1 transposition. Significance: MOV10 contributes to the cellular control of LINE-1 replication. LINE-1 (long interspersed element 1) is an autonomous nonlong terminal repeat retrotransposon. Its replication often causes mutation and rearrangement of host genomic DNA. Accordingly, host cells have evolved mechanisms to control LINE-1 mobility. Here, we report that a helicase named MOV10 effectively suppresses LINE-1 transposition. Mutating the helicase motifs impairs this function of MOV10, suggesting that MOV10 requires its helicase activity to suppress LINE-1 replication. Further studies show that MOV10 post-transcriptionally diminishes the level of LINE-1 RNA. The association of MOV10 with both LINE-1 RNA and ORF1 suggests that MOV10 interacts with LINE-1 RNP and consequently causes its RNA degradation. These data demonstrate collectively that MOV10 contributes to the cellular control of LINE-1 replication.

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 it
