Drosophila genome-wide UMI-STARR-seq enhancer activity maps

DeepSTARR predicts enhancer activity from DNA sequence and enables the de novo design of synthetic enhancers

A sheared genomic DNA library from Drosophila melanogaster strain y; cn bw sp was tested in S2 cells with DSCP developmental and Rps12 housekeeping core promoters in two biological replicates. The processed table contains merged developmental and housekeeping peak calls and their RNA/input enrichment measurements.

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

Episomal Drosophila STARR-seq vectors carried either the developmental DSCP or housekeeping Rps12 core promoter. Genomic inserts averaged approximately 200 bp; reporter RNA received a 10-bp UMI, and RNA and DNA input were sequenced as paired-end UMI-STARR-seq libraries. Peak activity is reported as non-corrected STARR-seq/input enrichment, while the corrected lower 95% confidence-bound enrichment was used for enhancer calling.

Column dictionary · 13 definitions
element_id
Unique screen-specific identifier for a called genomic enhancer peak.
locus_id
Genomic locus represented as chromosome:summit coordinate; the same locus can occur in both promoter screens.
chrom
Drosophila dm3 chromosome or chromosome arm containing the peak summit.
summit
Peak summit coordinate from the merged GEO peak call.
screen
Core-promoter screen: developmental (DSCP) or housekeeping (Rps12).
starrseq_reads_summit
Merged STARR-seq reporter-read count at the peak summit.
input_reads_summit
Merged plasmid DNA input-read count at the peak summit.
starrseq_reads_total
Total merged STARR-seq reporter reads in the corresponding screen.
input_reads_total
Total merged plasmid DNA input reads in the corresponding screen.
enrichment_starrseq_over_input
Non-corrected STARR-seq/input enrichment at the peak.
corrected_enrichment_lower_95ci
Conservative lower bound of the 95% confidence interval for enrichment, used for peak QC.
p_value
Hypergeometric peak-call p-value.
qc_pass
TRUE for peaks retained after the author-reported p-value and corrected-enrichment filters.

Quality control

Author-reported processing mapped paired-end reads to dm3 with Bowtie, retained mappings with at most three mismatches and insert size at most 2 kb, collapsed RNA reads at identical positions by 10-bp UMI allowing one mismatch, retained 150-250-bp fragments, excluded chromosomes U, Uextra and mitochondrial DNA, and pooled the two biological replicates per promoter. Enhancer peaks were called with hypergeometric p-value <= 0.001 and corrected enrichment over input >3; the GEO peak files and this table retain only entries meeting those thresholds.

Curation notes

The paper calls this a genome-wide UMI-STARR-seq assay; the processed table uses the two GEO merged peak files (11,658 developmental and 7,062 housekeeping peaks), one row per screen-specific peak. The generic S2 cell line description was mapped to canonical Schneider 2 in Cellosaurus (CVCL:Z232); the paper does not specify a more precise S2 isolate. The complete author sequence-level activity/prediction table is retained in raw_data for users who need 249-bp sequences and model predictions.
