title: Close encounters between active genes in the nucleus.
abstract: A recent paper demonstrates that coregulated genes on different chromosomes show surprisingly high frequencies of colocalization within the nucleus; this complements similar results found previously for genes localized tens of megabases apart on a single chromosome. Colocalization could be related to the earlier observation of active genes associating with foci where RNA polymerase II is concentrated.
