R1-DHS: accessibility-guided synthetic enhancers

Iterative deep learning-design of human enhancers exploits condensed sequence grammar to achieve cell type-specificity

A 200-bp synthetic enhancer library designed from chromatin-accessibility modeling and tested in parallel in HepG2 and K562 cells. The table contains deposited DNA/RNA counts, derived activity, and repository-provided design/effect annotations.

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 cell culture

Enhancer sequences were cloned upstream of a minimal promoter and reporter with multiple 3-prime UTR barcodes; reporter RNA and plasmid DNA were sequenced after transfection.
