Experiment / E5TPZ01BX5' UTR / Translation Efficiency MPRA (MPTA)

Zebrafish 5'UTR library polysome profiling in HEK293T cells at 12 hpt

NaP-TRAP reveals the regulatory grammar in 5’UTR-mediated translation regulation during zebrafish development

The zebrafish 5'UTR tiled reporter library was transfected into HEK293T cells and fractionated by sucrose-gradient polysome profiling 12 hours post-transfection. The table reconstructs the reporter-level fraction distributions and mean ribosome load (MRL) used to benchmark NaP-TRAP.

Processed tables are specific to each experiment. Column names, units, measurements, and table structure are not standardized across the database. Check this experiment’s column definitions and quality-control notes before comparing or combining data.

Perturbation & assay details

Basal / Untreated

HEK293T cells received in vitro transcribed zebrafish 5'UTR reporters and were fractionated after cycloheximide arrest. Each reporter's count was normalized within fraction, renormalized across the 13 analyzed fractions, and weighted by the reported ribosome-load labels (r1 through r11) to calculate MRL.

Quality control

The published MRL calculation retained 9,531 biological reporter entries present in every one of the 13 analyzed fractions (Fractions 11, 12, and 15-25). Spike-ins were excluded from the table. Fraction 26 (AGR004823) is retained in raw_data but excluded from MRL because it is absent from the published configuration and supplementary MRL table.

Curation notes

The data hub lists AGR004823 as Fraction 26, but the repository build configuration omits it and the supplied MRL workbook has 13 physical fractions grouped as r1, r2, r3, r4, r5, r6.5, r7.5, r9, and r11. The package follows that published convention. Assay organism is human HEK293T; inserts derive from zebrafish transcript 5'UTRs.
