Pathways for compartmentalizing protein synthesis in eukaryotic cells: the template-partitioning model
Bibliographic record
Abstract
mRNAs encoding signal sequences are translated on endoplasmic reticulum (ER) -- bound ribosomes, whereas mRNAs encoding cytosolic proteins are translated on cytosolic ribosomes. The partitioning of mRNAs to the ER occurs by positive selection; cytosolic ribosomes engaged in the translation of signal-sequence-bearing proteins are engaged by the signal-recognition particle (SRP) pathway and subsequently trafficked to the ER. Studies have demonstrated that, in addition to the SRP pathway, mRNAs encoding cytosolic proteins can also be partitioned to the ER, suggesting that RNA partitioning in the eukaryotic cell is a complex process requiring the activity of multiple RNA-partitioning pathways. In this review, key findings on this topic are discussed, and the template-partitioning model, describing a hypothetical mechanism for RNA partitioning in the eukaryotic cell, is proposed.

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.
