Experiment / E6SL1RPHZ5' UTR / Translation Efficiency MPRA (MPTA)

Zebrafish 5'UTR NaP-TRAP at 2 hpf with SV40 polyadenylation signal

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

A 124-nt library tiled the 5'UTRs of maternally supplied zebrafish transcripts plus IRES controls. The in vitro transcribed library was injected into single-cell embryos and translation was measured at 2 hpf using the SV40 reporter 3' processing configuration.

Perturbation & assay details

Basal / Untreated

In vitro transcribed 5'UTR mRNA reporters used a common Kozak/3xFLAG-GFP-PEST reporter with an SV40 polyadenylation signal. Anti-FLAG nascent-chain pulldown and input counts were normalized to spike-in reporters; ntrap_spike_3 was excluded as specified by the paper.

Quality control

ReadKnead/Bowtie2 mapping and UMI deduplication were used by the study, with UMIs within Hamming distance less than 2 collapsed. Counts were spike-normalized after excluding ntrap_spike_3. Only reporters with at least 100 unique input reads in each of B1 and B2 were retained (9,999 reporters).

Curation notes

The data-hub run table repeats the poly(A) run IDs for its SV40 rows; this package uses the distinct SV40 mapping from the repository configuration and supplied processed workbook: AGR003827/AGR003828 input and AGR003831/AGR003832 pulldown.
