The nuclear envelope in higher plant mitosis and meiosis [PDF]
Nucleus, 2019 Mitosis and meiosis in higher plants involve significant reconfiguration of the nuclear envelope and the proteins that interact with it. The dynamic series of events involves a range of interactions, movement, breakdown, and reformation of this complex ...

Recent advances in understanding the biological roles of the plant nuclear envelope
Nucleus, 2020 The functional organization of the plant nuclear envelope is gaining increasing attention through new connections made between nuclear envelope-associated proteins and important plant biological processes.

Cell migration in dense microenvironments
Comptes Rendus Biologies, 2023 The nucleus has been viewed as a passenger during cell migration that functions merely to protect the genome. However, increasing evidence shows that the nucleus is an active organelle, constantly sensing the surrounding environment and translating ...

Dystonia and the Nuclear Envelope [PDF]
Neuron, 2005 Mutations in torsinA cause dominantly inherited early-onset torsion dystonia in humans. In this issue of Neuron, Goodchild et al. show that torsinA knockout and knockin mice have similar phenotypes, which suggests that the mutant torsinA allele causes disease because it has decreased function. The experiments also highlight the possible role of nuclear

Interplay of the nuclear envelope with chromatin in physiology and pathology
Nucleus, 2020 The nuclear envelope compartmentalizes chromatin in eukaryotic cells. The main nuclear envelope components are lamins that associate with a panoply of factors, including the LEM domain proteins.

Nuclear envelope budding and its cellular functions
Nucleus, 2023 The nuclear pore complex (NPC) has long been assumed to be the sole route across the nuclear envelope, and under normal homeostatic conditions it is indeed the main mechanism of nucleo-cytoplasmic transport.

The Plant Nuclear Envelope and Its Role in Gene Transcription
Frontiers in Plant Science, 2021 Chromosomes are dynamic entities in the eukaryotic nucleus. During cell development and in response to biotic and abiotic change, individual sections as well as entire chromosomes re-organise and reposition within the nuclear space.

TorsinA in the nuclear envelope [PDF]
Proceedings of the National Academy of Sciences, 2004 Early-onset torsion dystonia, a CNS-based movement disorder, is usually associated with a single amino acid deletion (ΔE302/303) in the protein torsinA. TorsinA is an AAA+ ATPase in the endoplasmic reticulum, but what it does is unknown. Here, we use torsinA mutants with defects in ATP hydrolysis (E171Q, ATP-bound) and ATP binding (K108A, ATP-free) to ...

Specific nuclear envelope transmembrane proteins can promote the location of chromosomes to and from the nuclear periphery [PDF]
, 2013 BACKGROUND: Different cell types have distinctive patterns of chromosome positioning in the nucleus. Although ectopic affinity-tethering of specific loci can be used to relocate chromosomes to the nuclear periphery, endogenous nuclear envelope proteins ...

Cold Spring Harbor Perspectives in Biology, 2010 The nuclear envelope (NE) is a highly regulated membrane barrier that separates the nucleus from the cytoplasm in eukaryotic cells. It contains a large number of different proteins that have been implicated in chromatin organization and gene regulation.
