Ensemble conformations of human Chromosome 19 generated by computer simulations

The yellow bundle in the foreground represents a coarse-grained, computer-generated conformation of human Chromosome 19. The structure was obtained by using steered molecular dynamics simulations to enforce a comprehensive set of knowledge-based constraints. Specifically, the simulations were used to promote the spatial proximity of hundreds of gene pairs that are known to be significantly co-regulated. Conformations were obtained with LAMMPS and visualized by VMD. See Di Stefano, et al.
