The nuclei of multinucleated skeletal muscles experience substantial external force during development and muscle contraction. Protection from such forces is partly provided by lamins, intermediate filaments that form a scaffold lining the inner nuclear ...

The cell nucleus is constantly subjected to externally applied forces. During metazoan evolution, the nucleus has been optimized to allow physical deformability while protecting the genome under load.

Lamin A, lamin B, and lamin B receptor analogues in yeast. [PDF]
Previous studies have shown that turkey erythrocyte lamin B is anchored to the nuclear envelope via a 58-kD integral membrane protein termed p58 or lamin B receptor (Worman H. J., J. Yuan, G. Blobel, and S. D. Georgatos. 1988. Proc. Natl. Acad. Sci. USA. 85:8531-8534). We now identify a p58 analogue in the yeast Saccharomyces cerevisiae.

Lamins are intermediate filaments that form a complex meshwork at the inner nuclear membrane. Mammalian cells express two types of Lamins, Lamins A/C and Lamins B, encoded by three different genes, LMNA, LMNB1 and LMNB2.

Lamins and lamin-associated proteins
A variety of morphological and biochemical studies have established that the nuclear lamins play an important role in nuclear structure and dynamics. Recent work reveals the existence of specialized lamin isotypes and novel pathways of modulation of lamin import into the nucleus via phosphorylation by protein kinase C.

Chromosome positioning is largely unaffected in lymphoblastoid cell lines containing emerin or A-type lamin mutations [PDF]
Gene-poor human chromosomes are reproducibly found at the nuclear periphery in proliferating cells. There are a number of inner nuclear envelope proteins that may have roles in chromosome location and anchorage, e.g. emerin and A-type lamins.

Lamins, the major components of the nuclear lamina, have gained rapidly increasing interest over the past decade as lamin mutations were found to cause numerous devastating diseases. These laminopathies include Emery–Dreifuss muscular dystrophy (EDMD), dilated cardiomyopathy type 1A, limb ...

Probing the environment of emerin by Enhanced ascorbate peroxidase 2 (APEX2)-mediated proximity labeling. [PDF]
Emerin is one of the best characterized proteins of the inner nuclear membrane, but can also occur at the level of the endoplasmic reticulum. We now use enhanced ascorbate peroxidase 2 (APEX2) to probe the environment of emerin.

Nuclear lamin phosphorylation: an emerging role in gene regulation and pathogenesis of laminopathies
Decades of studies have established that nuclear lamin polymers form the nuclear lamina, a protein meshwork that supports the nuclear envelope structure and tethers heterochromatin to the nuclear periphery.

The innate immunity adaptor SARM translocates to the nucleus to stabilize lamins and prevent DNA fragmentation in response to pro-apoptotic signaling. [PDF]
Sterile alpha and armadillo-motif containing protein (SARM), a highly conserved and structurally unique member of the MyD88 family of Toll-like receptor adaptors, plays an important role in innate immunity signaling and apoptosis.
