Experiment / E67AY5RGSPromoter / Core Promoter MPRA

COF-STAP-seq focused core-promoter screen in human HCT116 cells

Transcriptional cofactors display specificity for distinct types of core promoters

A 12,000-element representative human promoter/enhancer/control oligonucleotide library was assayed in HCT116 cells with GAL4-DBD recruitment of five human cofactors, P65, and GFP. Each condition was measured in three biological replicates by UMI-collapsed STAP-seq.

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 human cofactor recruitment; P65 positive and GFP negative controls

Episomal promoter/core-promoter MPRA using pSTAP-seq_human-4xUAS (Addgene 125150) with GAL4-DBD recruitment. The 133 bp human candidate fragments were selected from promoter, enhancer, and control classes, pooled with mouse promoter spike-ins, and reporter RNAs were UMI/sample-barcoded, sequenced, spike-in normalized, and averaged across three biological replicates. Conditions represented in the processed table: MED15, BRD4, EP300, MLL3, EMSY, P65, and GFP.

Quality control

The authors used UMI-collapsed triplicate STAP-seq counts and spike-in normalization. Because no condition-specific activated-CP table was deposited for this validation screen, this package applied the available row-level portion of the authors' support filter: at least 5 unique tags in at least 2 of 3 biological replicates for at least one non-GFP condition (P65 included as the positive control). The aggregate GEO table does not permit independent verification of the >=3-tags-at-one-TSS or Student's t-test/FDR components. 11,729 of 12,000 source rows retained and 271 excluded.

Curation notes

Source GEO accession: GSE126221. The focused human library includes promoter, enhancer, and random control sequences rather than only canonical promoters. No author-defined activated-CP table was provided for the HCT116 screen, so the available row-level portion of the published support filter was applied. 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.
