While by the PICh approach several hundreds of putative telomere-associated factors were identified and the PICh technique is, in general, addressing the global composition of (telomeric) chromatin, our approach is more apt to rapidly identify the direct DNA binders and their tight interaction partners as illustrated by the identification of HOT1.
The ubiquitin specific protease USP7 (also called HAUSP) is known to associate with PML-NBs and to be a tight binding partner of two herpesvirus proteins that disrupt PML NBs.
This result indicates that Sirt3 is likely a selective and relatively tight binding partner of H3K4Cr.
In addition to the established telomere-binding proteins and their tight interaction partner, we have identified HOT1 as the first direct telomere-binder that positively regulates telomere length.
In vitro data indicate that in the presence of other tight-binding partners, cross-reactivity of 18 and 21 is minimized.

(A ) A two-dimensional plot showing the Log2 values of the stable isotope labeling of amino acids in cell culture (SILAC) ratios (heavy/light (H/L)) of each identified protein for the 'selectivity filter' (x axis) and 'affinity filter' (y axis) experiments.
Tim Minchin's ebullient music and lyrics add to the gaiety of the show while inevitably shifting the focus at times away from Matilda: we get, for instance, an extended interlude in which Matilda's mum and her tight-trousered partner do a florid Latinate number that could easily fit into Strictly Come Dancing.
Money was tight, and the partners ran the company from their homes for years, only getting an office in 2008.
Much like Ford and Toyota developed impenetrable process moats through tight integration of partners, suppliers, and unique internal processes, systems of intelligence forge barracks through the perfect portmanteau of data, algorithms, domain expertise, and data-driven product design.
On that note, it will be interesting to see how TransferWise continues to walk the tight rope of partnering whilst, in some ways and with increasing feature parity, competing with the same potential partners.
