Abstract
The nucleus is a highly structured organelle with many chromatin and protein compartments that partition the genome into regulatory domains. One such a compartment within the mammalian nucleus is the microenvironment underlying the nuclear envelope (NE) where intermediate filament proteins, lamins, act as a link between cytoskeletal and inner nuclear membrane (INM) proteins, chromatin binders and modifiers, and heterochromatin. These dynamic interactions regulate many cellular processes and, when they are perturbed, can lead to genome dysregulation and disease.
