A role for nuclear lamins in nuclear envelope assembly [PDF]

The Journal of Cell Biology, 2001
The molecular interactions responsible for nuclear envelope assembly after mitosis are not well understood. In this study, we demonstrate that a peptide consisting of the COOH-terminal domain of Xenopus lamin B3 (LB3T) prevents nuclear envelope assembly in Xenopus interphase extracts.

Nuclear lamins: building blocks of nuclear architecture [PDF]

Genes & Development, 2002
Nuclear lamins were initially identified as the major components of the nuclear lamina, a proteinaceous layer found at the interface between chromatin and the inner nuclear membrane (Fawcett 1966). Due to their position at the periphery of the nucleus, lamins were originally proposed to support the nuclear envelope and provide anchorage sites for ...

Myopathic lamin mutations cause reductive stress and activate the nrf2/keap-1 pathway. [PDF]

PLoS Genetics, 2015
Mutations in the human LMNA gene cause muscular dystrophy by mechanisms that are incompletely understood. The LMNA gene encodes A-type lamins, intermediate filaments that form a network underlying the inner nuclear membrane, providing structural support ...

Modulation of muscle redox and protein aggregation rescues lethality caused by mutant lamins

Redox Biology, 2021
Mutations in the human LMNA gene cause a collection of diseases called laminopathies, which includes muscular dystrophy and dilated cardiomyopathy. The LMNA gene encodes lamins, filamentous proteins that form a meshwork on the inner side of the nuclear ...

Lamins A and C but Not Lamin B1 Regulate Nuclear Mechanics [PDF]

Journal of Biological Chemistry, 2006
Mutations in the nuclear envelope proteins lamins A and C cause a broad variety of human diseases, including Emery-Dreifuss muscular dystrophy, dilated cardiomyopathy, and Hutchinson-Gilford progeria syndrome. Cells lacking lamins A and C have reduced nuclear stiffness and increased nuclear fragility, leading to increased cell death under mechanical ...

The Role of Lamins in the Nucleoplasmic Reticulum, a Pleiomorphic Organelle That Enhances Nucleo-Cytoplasmic Interplay

Frontiers in Cell and Developmental Biology, 2022
Invaginations of the nuclear membrane occur in different shapes, sizes, and compositions. Part of these pleiomorphic invaginations make up the nucleoplasmic reticulum (NR), while others are merely nuclear folds.

Glycosylated forms of nuclear lamins

FEBS Letters, 1989
Chromatin and pore complex‐lamina preparations were obtained from pig and chicken tissues, and their proteins were analysed by mono‐ and bidimensional electrophoresis. A glycosylated form of lamin A, recognized by concanavalin A, was shown to be present in at least 3 of the tissues examined.

Aging and nuclear organization: lamins and progeria [PDF]

Current Opinion in Cell Biology, 2004
The discoveries of at least eight human diseases arising from mutations in LMNA, which encodes the nuclear A-type lamins, have revealed the nuclear envelope as an organelle associated with a variety of fundamental cellular processes. The most recently discovered diseases associated with LMNA mutations are the premature aging disorders Hutchinson ...

A novel role of lamins from genetic disease to cancer biomarkers

Oncology Reviews, 2016
Lamins are the key components of the nuclear lamina and by virtue of their interactions with chromatin and binding partners act as regulators of cell proliferation and differentiation.

Regulation of Lipid Metabolism by Lamin in Mutation-Related Diseases

Frontiers in Pharmacology, 2022
Nuclear lamins, known as type 5 intermediate fibers, are composed of lamin A, lamin C, lamin B1, and lamin B2, which are encoded by LMNA and LMNB genes, respectively.
