Dynamic SUMO remodeling drives a series of critical events during the meiotic divisions in Caenorhabditis elegans. [PDF]
PLoS Genetics, 2018 Chromosome congression and segregation in C. elegans oocytes depend on a complex of conserved proteins that forms a ring around the center of each bivalent during prometaphase; these complexes are then removed from chromosomes at anaphase onset and ...

The Anaphase-Promoting Complex [PDF]
Molecular Cell, 2002 Key events in mitosis such as sister chromatid separation and subsequent inactivation of cyclin-dependent kinase 1 are regulated by ubiquitin-dependent proteolysis. These events are mediated by the anaphase-promoting complex (APC), a cell cycle-regulated ubiquitin ligase that assembles multiubiquitin chains on regulatory proteins such as securin and ...

Interaction Between Actin and Microtubules During Plant Development
Cytoskeleton, EarlyView.ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

Chiasmata promote monopolar attachment of sister chromatids and their co-segregation toward the proper pole during meiosis I. [PDF]
PLoS Genetics, 2011 The chiasma is a structure that forms between a pair of homologous chromosomes by crossover recombination and physically links the homologous chromosomes during meiosis. Chiasmata are essential for the attachment of the homologous chromosomes to opposite

Cell Division: SACing the Anaphase Problem [PDF]
Current Biology, 2014 Errors in chromosome segregation are safeguarded by the spindle assembly checkpoint. Yet the very defects that trigger this checkpoint are inescapable consequences of sister chromatid segregation in anaphase. Three new studies provide clues to how cells cope with this problem.

Mechanical Coupling With the Nuclear Envelope Shapes the Schizosaccharomyces pombe Mitotic Spindle
Cytoskeleton, EarlyView.ABSTRACT The fission yeast Schizosaccharomyces pombe divides via closed mitosis, meaning that spindle elongation and chromosome segregation transpire entirely within the closed nuclear envelope. Both the spindle and nuclear envelope must undergo shape changes and exert varying forces on each other during this process.

MethodsX, 2018 Immunofluorescence staining is used extensively to examine various types of cellular events. However, even when an antibody can detect its epitopes in western blotting, it sometimes fails to detect its epitopes when used for immunofluorescence staining ...

Nature Communications, 2020 Meiotic cell division in oocytes is asymmetric and requires microtubule spindle migration after anaphase-onset. Here, the authors show that Nampt, an enzyme of the Nicotinamide adenine dinucleotide (NAD) biosynthetic pathway, contributes to post-anaphase

The FEAR protein Slk19 restricts Cdc14 phosphatase to the nucleus until the end of anaphase, regulating its participation in mitotic exit in Saccharomyces cerevisiae. [PDF]
PLoS ONE, 2013 In Saccharomyces cerevisiae mitosis, the protein Slk19 plays an important role in the initial release of Cdc14 phosphatase from the nucleolus to the nucleus in early anaphase, an event that is critical for proper anaphase progression. A role for Slk19 in
