Experiment / E4WPTA4FJStandard STARR-seq

WT enhancer-pair library, developmental core promoter in ecdysone-treated S2 cells

Developmental and housekeeping transcriptional programs display distinct modes of enhancer-enhancer cooperativity in Drosophila

The 1000-oligo wild-type/control pair library was assayed toward DSCP in S2 cells treated with 20-hydroxyecdysone after electroporation. The deposited table contains 716,152 oriented pair measurements and includes ecdysone-inducible candidate sequences.

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

~42 μM 20-hydroxyecdysone for 24 h after electroporation

Custom UMI-STARR-seq/peSTARR-seq assay: 249-bp candidate oligos were fused in defined 5′ and 3′ positions around an inert spacer, cloned downstream of a Drosophila core promoter, and quantified by internally normalized reporter RNA/input DNA sequencing. The processed source table reports DESeq2-normalized inferred individual activities and paired RNA/input log2 fold changes. Cells received approximately 42 μM 20-hydroxyecdysone after the one-hour recovery period and were collected at 24 h.

Column dictionary · 28 definitions
left_element_id
Identifier of the sequence in the 5′/left position of the tested oriented pair.
right_element_id
Identifier of the sequence in the 3′/right position of the tested oriented pair.
left_sequence_group
Sequence class/group from the corresponding oligo design sheet for the left element.
left_sequence_detail
More specific design category from the corresponding oligo design sheet for the left element.
left_chromosome
Chromosome/contig label for the left oligo design; may be blank for synthetic or unavailable coordinates.
left_start
Start coordinate of the left oligo in the stated reference assembly.
left_end
End coordinate of the left oligo in the stated reference assembly.
left_strand
Strand of the left oligo design.
right_sequence_group
Sequence class/group from the corresponding oligo design sheet for the right element.
right_sequence_detail
More specific design category from the corresponding oligo design sheet for the right element.
right_chromosome
Chromosome/contig label for the right oligo design; may be blank for synthetic or unavailable coordinates.
right_start
Start coordinate of the right oligo in the stated reference assembly.
right_end
End coordinate of the right oligo in the stated reference assembly.
right_strand
Strand of the right oligo design.
left_robust_control
TRUE when the left sequence passed the authors’ robust negative-control z-score filter.
right_robust_control
TRUE when the right sequence passed the authors’ robust negative-control z-score filter.
left_activity_log2
DESeq2-normalized inferred individual activity of the left sequence, expressed as log2 activity relative to the core-promoter negative-control baseline.
left_activity_fdr
FDR-adjusted one-sided test for left individual activity versus robust control pairs.
right_activity_log2
DESeq2-normalized inferred individual activity of the right sequence, expressed as log2 activity relative to the core-promoter negative-control baseline.
right_activity_fdr
FDR-adjusted one-sided test for right individual activity versus robust control pairs.
pair_activity_log2
DESeq2 log2 fold change for reporter RNA versus input DNA for the tested pair.
pair_activity_fdr
DESeq2 FDR-adjusted significance value for the paired reporter activity; blank means the pair FDR was not estimable in the deposited table.
pair_fdr_estimable
TRUE when pair_activity_fdr is numeric and FALSE when it is blank/not estimable.
left_activity_class
Inactive/Low/Medium/Strong class using authors’ activity rule: log2 activity >1 and FDR <0.05, with cut points at 2 and 4.
right_activity_class
Inactive/Low/Medium/Strong class using authors’ activity rule: log2 activity >1 and FDR <0.05, with cut points at 2 and 4.
left_active
TRUE when left_activity_log2 >1 and left_activity_fdr <0.05.
right_active
TRUE when right_activity_log2 >1 and right_activity_fdr <0.05.
pair_fdr_significant
TRUE when pair_activity_fdr <0.05, FALSE when it is numeric and ≥0.05, and blank when pair FDR is not estimable.

Quality control

Author QC was retained: heterotypic pairs required at least 5 UMI-collapsed reads in each input replicate; pair activity was computed with a pseudocount using DESeq2 with at least two replicates; normalization used robust negative-control pair counts; control sequences were retained when their mean control-pair activity z-score was between −1 and 1; individual activity required at least 10 robust controls; and homotypic pairs and pairs lacking either individual activity were removed. Active individual sequences were defined as log2 activity >1 with FDR <0.05. Package QC additionally retained only rows with finite left/right individual activity and finite pair log2 activity. No rows were removed by this final check in these deposited FC tables. Missing pair FDRs are retained as not estimable rather than treated as a failed activity measurement.

Curation notes

Source: GEO GSE245033_WT_oligo_pool_dCP_S2_ecdysone_FC_table.txt.gz. The package retained 716,152 of 716,152 deposited rows after the finite-activity check (filtered: 0; unmapped sequence IDs: 0). 55,029 retained rows have no estimable pair FDR in the deposited table; their pair_activity_log2 values remain usable. Sequence classes and coordinates are joined from the compact exported design sheet in raw_data.
