Chromatin interactions with HIF-binding sites are pre-established in normoxia.Figure 3A) Capture-C tracks (averaged across the two replicates) from normoxic (red) and hypoxic (inverted in blue) MCF-7 cells are shown for each HIF-binding site captured.B) The interaction frequency (normalized to the number of informative reads in each dataset and to the expected distribution of counts at a given distance from the capture site) in hypoxia (vertical axis) was plotted against that in normoxia (horizontal axis) for each site that interacted significantly with a HIF-binding site in either normoxia or hypoxia or both. Highlighted in red are sites that had a significantly different interaction frequency in either condition.C) CTCFChIP-seq peaks immediately flanking the captured HIF-binding sites were identified and the average normalized CTCFChIP-seq signal (RPKM) was plotted for normoxic (red) and hypoxic (blue) MCF-7 cells.

The human kinase yeast array as a tool to identify the kinase(s) modulating a phosphorylation-dependent PPIs.Figure 4A. Two distinct cases of phosphorylation‑dependent interaction modulation. Loss of interaction: the phosphorylation of one protein (A) by the active kinase results in the loss of interaction with the second protein (B) and therefore in no growth on selective media. Gain of interaction: Co-expression of an active kinase with a Y2H bait-prey protein pair can lead to phosphorylation of one protein partner (A) promoting the pS/T-dependent interaction with protein (B). In the phospho-Y2H approach, gain of interaction results in yeast growth on selective media. B. Systematic phospho-Y2H interaction mating approach to identify the active kinase(s) modulating phosphorylation-dependent PPI. One yeast strain (L40matα) co-expressing the interacting bait and prey proteins and was mated against the 266 kinases in the array (L40mata) in a pairwise manner. The growth patterns of the diploid yeast strains that express bait, prey and one kinase from a third plasmid, indicate phospho-modulation of protein interactions.
