Profiling the regulatory capacity of genomic sequences using a massively parallel reporter assay. (a) Schematic of MPRA oligonucleotide library design. (b) Schematic of MPRA vector design and cloning. (c) Abundance of MPRA library elements corresponding to genomic sequences represented in the MPRA plasmid pool (pDNA, technical replicates) and expressed in HEK293T (cDNA, biological replicates). (d) Reproducibility of MPRA library element detection across biological replicates. (e) Regulatory activity of reference genome sequences profiled in MPRA (red = significant regulatory activity). (f) Fraction of reference genome sequences that display significant regulatory activity in MPRA. (g) Distance to nearest TSS for reference genome sequences that display significant regulatory activity.
