Experiment / E6DU9Z2DGPromoter / Core Promoter MPRA

COF-STAP-seq genome-wide core-promoter screen in Drosophila S2 cells

Transcriptional cofactors display specificity for distinct types of core promoters

A 72,000-element Drosophila core-promoter oligonucleotide library was assayed in S2 cells while individual GAL4-DBD-tethered cofactors were recruited to a 4xUAS reporter. Three biological replicates were generated for 23 cofactors plus P65 and GFP controls, and productive reporter initiation was quantified by UMI-collapsed STAP-seq tags.

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

GAL4-DBD-tethered Drosophila cofactor recruitment; P65 positive and GFP negative controls

Episomal promoter/core-promoter MPRA using pSTAP-seq_fly-4xUAS (Addgene 125149). Candidate inserts are 133 bp genomic DNA fragments centered on major TSSs, pooled with Drosophila pseudoobscura spike-in CPs, and co-transfected with GAL4-DBD-cofactor expression plasmids. Reporter RNA was captured with a 5-prime linker containing a 10-nt UMI and sample barcode; paired-end Illumina reads were UMI-collapsed, mapped to candidate oligos, spike-in normalized, and averaged across three biological replicates. Conditions represented in the processed table: 23 Drosophila cofactors (Nejire/P300, Mof, pCAF/Gcn5, Atac2, Tip60, Br140, Lpt, Trr, Trx, Brm, Chro, Brd8, Brd9, fs(1)h/Brd4, MED15, MED24, MED25, Taf4, Tbp, Trf2, EMSY, Gfzf and Pzg), P65, and GFP.

published_nonredundant_s2
TRUE when the candidate is in the authors’ nonredundant S2 activated-CP set (Supplementary Table 13); blank for non-S2 experiments.

TRUE for every row retained in this processed table after the experiment-specific QC filter.

Quality control

The authors retained CPs supported by >=5 unique reporter tags (with >=3 tags supporting a single TSS) in at least 2 replicates, tested each condition against GFP by one-sided Student's t-test with Benjamini-Hochberg correction, and called activation at FDR <=0.06 and fold-change >=2. This table uses the authors' published activated S2 CP set (Supplementary Table 11) as the QC-filtered population: 30,936 of 72,000 source rows retained and 41,064 excluded. The GEO source is aggregated per oligo, so the single-TSS support subcriterion cannot be independently rechecked here.

Curation notes

Source GEO accession: GSE116197. The GEO S2 unique-count file contains six GFP replicate columns (GFP_Rep1-6) and a nonstandard Tip60 replicate order; all source columns are retained with stable replicate numbering in the processed table. The S2 table is restricted to the authors' 30,936 activated CPs in Supplementary Table 11; the authors' 25,971-element nonredundant subset is exposed as a flag. Aggregate per-oligo counts cannot independently verify the paper's >=3-tags-at-one-TSS subcriterion. The processed table retains the authors' 30,936 activated CPs (Supplementary Table 11); 25,971 are also in their nonredundant Supplementary Table 13 set. Normalized activity values are reporter-tag counts rather than RNA/DNA ratios because STAP-seq reports productive initiation from the promoter library and does not use a DNA-input denominator in the deposited processed table.
