HaCaT endogenous p63-bound element STARR-seq

Crosstalk between paralogs and isoforms influences p63-dependent regulatory element activity

The five-variant p63-bound regulatory-element library was assayed in HaCaT transformed keratinocytes to examine epithelial-context dependence of p63RE activity. This processed table uses the author-filtered WT/mut matched subset and retains one row per enhancer family.

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; endogenous p63

The episomal pGB118 STARR-seq library used 119–120 bp inserts centered on a p63 response element (p63RE) from 17,310 genomic p63 ChIP-seq regions. For this cross-cell-line analysis, WT and GC-preserving p63RE-mutant constructs were paired; approximately 50 million cells per biological replicate were transfected by lipofection, harvested after 24 h, and poly(A)+ reporter RNA was sequenced as single-end 100-bp reads on an Illumina NextSeq 2000. Values in table.csv are the authors’ total-read-normalized RNA/DNA ratios from Supplementary Table S3, with the WT-versus-mutant log2 effect derived here.

Quality control

The authors mapped reads by exact pattern matching, removed regulatory elements with <2 CPM in the plasmid DNA library or <0.1 CPM in the cDNA library, and normalized reads to the total reads per sample before averaging replicate expression values. For this cross-cell-line view, only elements with matched WT and mut records in both DNA and RNA libraries were retained (9,697 element families; 19,394 rows for HaCaT in Supplementary Table S3). The package additionally required a complete WT/mut family and non-missing RNA/DNA values; no further biological-activity filter was applied.

Curation notes

HaCaT is the transformed human keratinocyte line Cellosaurus CVCL:0038. The processed table is the authors’ 9,697-element WT/mut-only subset used for Figure 5 comparisons, rather than the larger five-variant MCF10A/p53KO subset.
