The nuclear lamina is a fibrous structure located on the internal surface of the nuclear envelope of only multicellular eukaryotes. It is composed of several forms of the intermediate protein filament, laminin, and laminin-associated proteins.
One of its functions is to tether chromatin to the nuclear envelope thereby organizing chromatin and controlling gene expression. Heterochromatin, chromatin that is infrequently used, is preferentially located near the nuclear periphery.
The nuclear lamina also acts to support nuclear shape. Mutations in genes responsible for the formation of this lamina cause abnormally shaped nuclei and pathologies such as Hutchinson-Gilford progeria syndrome. This syndrome is characterized by greatly accelerated aging.
