Systematic dissection of regulatory motifs in 2,000 predicted human enhancers using a massively parallel reporter assay
We employ a massively parallel reporter assay (MPRA) to measure the ex vivo activities of hundreds of K562 and HepG2 enhancers with known transcription factor motif instances. For seven selected motifs that correspond to known or predicted activators and repressors in the two cell types, we make directed modifications of the bases corresponding to these motifs and observe the changes in enhancer activity.

Deep data QC
metadata only · no data-level QC for this typeStandardized, field-standard QC computed by touching the data — every metric states how it was obtained
No quantitative QC rubric exists for this data type yet, so it is deliberately left unscored — this is an honest "not applicable", not a poor rating.
measured = computed from the data · extrapolated/reported = derived or from the repository · dq-1.0 · provisional — verify independently
