B. Schematic view of PAQR3 exon 1 and proximal promoter on chromosome 4 (hg19 assembly), obtained with the UCSC genome browser (https://genome.ucsc.edu/) and showing the sequence amplified in ChIP-qPCR assays in LCLs (thick black line) along with a previously described CHD7 ChIP-seq peak (thick grey line) and signal (green) in H1-hESC (ENCODE3).
