As the characteristic binding region for the PcG proteins is ∼50 nt, the clustering distance of 50 nt may be considered as optimal in this example.
For example, in a mammalian genome, there are about 10,000 binding regions for a TF.
Through reduced binding affinity of transcription factors to this region (for example, Ets-1), miR-146a expression was reduced [ 47].
Whether DGs that lack this region, for example the DGs of nematodes, have laminin-binding capacity will require direct experimental tests.
These data can then be quickly surveyed using the data browser and an Edit Mode track, and binding regions considered spurious (for example, those also observed in control experiments) or unreliable (for example, those observed in only one experimental replicate) can be flagged and then filtered using one of MochiView's data refinement utilities.
DNA methylation and histone modifications affect gene expression by changing the profiles of proteins that bind to specific DNA regions; for example, the binding profiles of transcription factors to promoter regions.
In silico promotor analyses of the KIAA1199 promoter region identified binding sites, for example, TP53, LEF1/TCF or SMAD4 (Supplementary Table 2).
Functional sites embedded within these regions, for example, binding sites that adopt a stable structure upon interactions, were shown to contribute to the organization of the complex or mediate interactions with transcriptional regulators.
However, it is becoming increasingly clear that certain TFs do require a particular set of histone TFs to access regulatory regions: MYC binding, for example, happens only in sites in which H3K4 and H3K79 methylations are abundant [25].
The user can limit a search to specific locations (for example, binding region calls from a ChIP experiment) or search the upstream regions of a list of specific genes.
