p63 isoform expression as estimated by Analysis Pipeline 2. Heatmap depicting the expression of p63 isoforms in FPKM (fragments per kilobase of transcript per million), across representative p63 expressing cell-lines. (PDF 44 kb
Additional file 5: Figure S3. of A global analysis of the complex landscape of isoforms and regulatory networks of p63 in human cells and tissues
ΔNp63α is the predominant isoform in both proliferating and differentiating keratinocytes. Line chart depicting expression of p63 isoforms in human keratinocytes at three time points during differentiation: Day 0(DK0), Day3 (DK3) and Day 6(DK6). ΔNp63α levels are attenuated during keratinocyte differentiation whereas TAp63 expression is not detectable at any time points under these conditions. Also shown are expression pattern of differentiation markers, FLG and EHF. FPKM: fragments per kilobase of transcript per million. (PDF 30 kb
Binding of IFI16 protein to supercoiled DNAs.
<p>(A) 100 ng sc pBluescript (lane 1–6) and sc pCMYC (lane 7–12) were incubated with increasing concentrations of IFI16 (molar ratio DNA:protein 1:0 / 1:1.25 / 1:2.5 / 1:5/ 1:10 / 1:20) in binding buffer (5 mM Tris-HCl, pH 7.0; 1 mM EDTA, 50 mM KCl and 0.01% Triton X-100) on ice for 15 min. The electrophoresis ran for 3 h at 100 V at 4°C. (B) 100 ng linear pBluescript (lane 1–6) and linear pCMYC (lane 7–12) were incubated with increasing concentrations of IFI16 (molar ratio DNA: protein 1:0 / 1:1.25 / 1:2.5 / 1:5/ 1:10 / 1:20) in binding buffer (5 mM Tris-HCl, pH 7.0; 1 mM EDTA, 50 mM KCl and 0.01% Triton X-100) on ice for 15 min. The electrophoresis ran for 3 h at 100 V at 4°C.</p
H/D exchange of IFI16 in response to DNA interaction.
<p>(A) H/D exchange of IFI16 in response to DNA interaction was analyzed in four reactions: IFI16 protein without DNA as a control, IFI16 with single stranded DNA oligonucleotide (SS DNA), IFI16 with double stranded DNA oligonucleotide (DS NHE III) and IFI16 with DNA forming quadruplex structure (Q NHEIII). H/D exchange was quenched at 900 s after addition of deuterium. The graph shows percentage deuteration of individual amino acids of IFI16 calculated as weighted average of corresponding peptides [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0157156#pone.0157156.ref053" target="_blank">53</a>]. Shaded area of the graph shows the areas not covered by peptides. The deuteration spectrum is aligned with the domain structure of IFI16 and with prediction of disordered regions (FoldIndex [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0157156#pone.0157156.ref054" target="_blank">54</a>]). (B) Structure of the first HIN-A domain (PDB 2OQ0) corresponding to amino acids 198–389 of IFI16 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0157156#pone.0157156.ref014" target="_blank">14</a>]. (C) Complex of the second HIN-B domain with DNA (PDB 3RNU) corresponding to amino acids 516–710 of IFI16 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0157156#pone.0157156.ref023" target="_blank">23</a>]. In (B) and (C) the helical linker peptide exhibiting the most significant changes in percentage of deuteration in the presence of quadruplex DNA is highlighted in red.</p
CD spectroscopy of quadruplexes and their stabilization by IFI16.
