The NLS3 Motif in TPX2 Regulates Spindle Architecture in Xenopus Egg Extracts

Cytoskeleton, EarlyView.
ABSTRACT A bipolar spindle composed of microtubules and many associated proteins functions to segregate chromosomes during cell division in all eukaryotes, yet both spindle size and architecture vary dramatically across different species and cell types.

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.

Dissecting the Structural Organization, Recruitment and Activation Mechanisms of Centrosomal γ‐TuRCs

Cytoskeleton, EarlyView.
ABSTRACT Visualizing human centrosomes using cryo‐electron tomography revealed the native structure and molecular organization of γ‐tubulin ring complexes (γ‐TuRCs). γ‐TuRCs localized to two distinct centrosomal pools, one in the pericentriolar material (PCM) and another in the centriole lumen, which is released during mitosis.

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

LZTS2 Negatively Regulates Centrosomal CEP135 Levels and Microtubule Nucleation

Cytoskeleton, EarlyView.
ABSTRACT The microtubule cytoskeleton is a fundamental functional component of the cell. In vertebrate proliferating cells, centrosomes are the primary microtubule organizing center (MTOC), and their dysregulation has been linked to genomic instability and cancer.
