}In metazoan cells, the heterochromatin is generally localized at the nuclear periphery, whereas active genes are preferentially found in the nuclear interior. In the present paper, we review current evidence showing that components of the nuclear lamina interact directly with heterochromatin, which implicates the nuclear lamina in a mechanism of specific gene retention at the nuclear periphery and release to the nuclear interior upon gene activation. We also discuss recent data showing that…

Specifying peripheral heterochromatin during nuclear lamina reassembly
- BiologyNucleus
- 2014
Evidence is obtained that a previously unstudied human protein, PRR14, participates in the tethering of heterochromatin to the inner nuclear periphery, and may play a role in specifying HP1-bound heterochROMatin for reattachment to the nuclear lamina at mitotic exit.
The PRR14 heterochromatin tether encodes modular domains that mediate and regulate nuclear lamina targeting
- BiologyJournal of Cell Science

It is shown that PRR14 associates dynamically with the nuclear lamina, and evidence that such dynamics are regulated through phosphorylation and dephosphorylation of the LBD is provided.
The PPR14 heterochromatin tether encodes modular domains that mediate and regulate nuclear lamina targeting

A centrally located, evolutionarily conserved PRR14 nuclear lamina binding domain (LBD) is identified that is both necessary and sufficient for positioning of PRR 14 at thenuclear lamina and the identification of a modular LBD may provide an engineering strategy for delivery of cargo to the Nuclear lamina.

Heterochromatin enhances the ability of the nuclear lamina to maintain the sturdiness and shape of the eukaryotic nucleus; a structural role for chromatin that is distinct from its genetic functions.

Three-dimensional DNA-immunoFISH is devised for inducible tethering of genes to the inner nuclear membrane (INM) and targeted adenine methylation is used to show that, as is the case for the model system, inactive immunoglobulin loci at the nuclear periphery are contacted by INM and lamina proteins.

Cells have evolved sophisticated multi-protein complexes that can regulate gene activity at various steps of the transcription process, and nuclear-pore components seem to not only recruit the RNA-processing and RNA-export machinery, but contribute a level of regulation that might enhance gene expression in a heritable manner.
