LINC complex regulation of genome organization and function
Current Opinion in Genetics & Development, 2021The regulation of genomic function is in part mediated through the physical organization and architecture of the nucleus. Disruption to nuclear organization and architecture is increasingly being recognized by its contribution to many diseases. The LINC complexes - protein structures traversing the nuclear envelope, that physically connect the nuclear ...

LINC complexes and nuclear positioning
Seminars in Cell & Developmental Biology, 2018One of the characteristics of eukaryotic cells is their structural plasticity associated with the ability to carry out a broad range of complex functions, both autonomously and as components of tissues and organs. Major cellular rearrangements can be observed in various systems from meiosis in fission yeast, through dermal differentiation in nematodes,

The LINC complex and human disease
Biochemical Society Transactions, 2011The LINC (linker of nucleoskeleton and cytoskeleton) complex is a proposed mechanical link tethering the nucleo- and cyto-skeleton via the NE (nuclear envelope). The LINC components emerin, lamin A/C, SUN1, SUN2, nesprin-1 and nesprin-2 interact with each other at the NE and also with other binding partners including actin filaments and B-type lamins ...

Apicomplexan parasites include some of the most important pathogens, such as Plasmodium spp., the causative agent of malaria, or Toxoplasma gondii, the causative agent of toxoplasmosis. As obligate intracellular parasites, Apicomplexa invade host cells in an active process, where they replicate within a parasitophorous vacuole, followed by egress and ...

The assembly of a noncanonical LINC complex in Saccharomyces cerevisiae
Current Genetics, 2021The linker of nucleoskeleton and cytoskeleton (LINC) complex is a protein complex across the nuclear envelope and has maintained its general assembly mode throughout evolution. SUN and KASH proteins, which are the major components of LINC complex, interact with each other in the nuclear lumen to transmit forces across the nuclear envelope and have ...

Role of LINC complex proteins in sperm formation
Medicine of Extreme Situations, 2022Spermatogenesis is characterized by the significant changes of three-dimensional organization of the nucleus in spermatocytes, spermatides and spermatozoa. The functional cooperation between the nuclear envelope proteins and the acroplaxome/manchette is essential for nuclear elongation, acrosome biogenesis, formation of the flagellum.

EM Tomography of Meiotic LINC Complexes
2018Electron microscope (EM) tomography is a powerful technique that enables the three-dimensional analysis of subcellular structures at high resolution. We have applied this method to the quantitative analysis of LINC complex distribution and interaction with the cytoskeleton in meiotic cells from male mice.

LINC complexes as regulators of meiosis
Current Opinion in Cell Biology, 2018Meiosis is a key processes of sexual reproduction in eukaryotes. By combining two cell division cycles with a single round of DNA replication meiosis provides a mechanism to generate haploid gametes. Coincidentally, processes involved in ensuring appropriate segregation of homologous chromosomes also result in genetic recombination and shuffling of ...

Functional Analysis of LINC Complexes in the Skin
2018The genome in eukaryotic cells is encased by two intricate and interconnected concentric membranes, which together with the underlying nuclear lamina form the nuclear envelope (NE). Two fundamental macromolecular structures are embedded within the nuclear envelope: the nuclear pore (NPC) and the LINC complex.

Analyzing Mechanotransduction Through the LINC Complex in Isolated Nuclei
2018The mechanical properties of the cellular microenvironment can impact many aspects of cell behavior, including molecular processes in the nucleus. Recent studies indicate that the LINC complex and its associated nuclear envelope transmit and transduce mechanical stress into biochemical pathways that ultimately regulate nuclear structure or gene ...
