We have analyzed publicly available K562 Hi-C data, which enables genome-wide unbiased capturing of chromatin interactions, using a Mixture Poisson Regression Model to define a highly specific set of interacting genomic regions. We integrated multiple ENCODE Consortium resources with the Hi-C data, ...

Polycomb Group (PcG) proteins regulate gene expression by modifying chromatin. A key PcG complex, PRC1, has two activities: a ubiquitin ligase activity for histone H2A, and a chromatin compacting/nucleosome bridging activity that can inhibit transcription and chromatin remodeling. In Drosophila, the...

Recent genome-scale ChIP-chip studies of transcription factors have shown that a low percentage of experimentally determined binding sites contain the consensus motif for the immunoprecipitated factor. In most cases, differences between in vivo target sites that contain or lack a consensus motif ha...
ORGANISM(S): Mus musculus 
Millions of cis-regulatory sequences have recently been found in the human genome, but the function of most cis-elements are not yet clear, in part due to the difficulty in determining their regulatory targets, which are often located millions of base pairs away and separated by one or more unrelate...
