We developed a general approach that combines Chromosome Conformation Capture Carbon Copy with the Integrated Modeling Platform to generate high-resolution three-dimensional models of chromatin at the Mb scale. We applied this approach to the ENm008 domain on human chromosome 16 containing the α-globin locus, which is expressed in K562 cells and silenced in lymphoblastoid cells (GM12878). The models accurately reproduce the known looping interactions between the α-globin genes and their distal regulatory elements. Further, we find that the domain folds into a single globular conformation in GM12878 cells, whereas two globules are formed in K562 cells. The central cores of these globules are enriched for transcribed genes, whereas non-transcribed chromatin is more peripheral. We propose that globule formation represents a higher-order folding state related to clustering of transcribed genes around shared transcription machineries, as observed by microscopy.
