The MOV10 Helicase Inhibits LINE-1 Mobility
Bibliographic record
Abstract
LINE-1 (long interspersed element 1) is an autonomous non-long 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. 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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
