There is growing recognition that the organization of nucleic acids and regulatory proteins is functionally linked to the assembly, localization and activity of gene regulatory machinery. Cellular, molecular, biochemical and in-vivo genetic evidence support an obligatory relationship between nuclear microenvironments where regulatory complexes reside and fidelity of transcriptional control. Perturbations...
Eukaryotic genomes are functionally compartmentalized into chromatin domains by their attachment to a supporting structure that has traditionally been termed the nuclear matrix. Present evidence indicates the dynamics of this entity, which requires particular properties of the elements that mediate this kind of interaction. Above all, this is enabled by the so-called 'mass binding phenomenon' by which...
