Abstract

fetched live from OpenAlex

Analysis of transcription profiles has been the focus of genome wide characterization of gene expression during the last decade. Downstream of transcription, regulation of translation represents a less explored step in the gene expression pathway. Differential translation can be caused by differential ribosome recruitment, translational elongation or termination although the ribosome recruitment step is thought to be the major source of differential translation. Genome wide studies of differential translation through analysis of ribosome recruitment in a variety of model systems indicate better correlation to protein levels as compared to transcriptional regulation. These studies also indicate translational control as a major transcript specific regulation step. Here we review the current literature on genome wide regulation of ribosome recruitment. We conclude that without considering regulation of ribosome recruitment, important information regarding the links between gene expression and protein levels is lost and that ribosome recruitment will be an integral part of a systems level understanding for regulation of gene expression.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
