Tubulin isotype regulation maintains asymmetric requirement for α-tubulin over β-tubulin
Journal of Cell Biology, 2023 How cells regulate α- and β-tubulin to meet the demand for αβ-heterodimers and avoid consequences of monomer imbalance is not understood. We investigate the role of gene copy number and how shifting expression of α- or β-tubulin genes impacts tubulin proteostasis and microtubule function in Saccharomyces cerevisiae.

Frontiers in Cell and Developmental Biology, 2022 In this work, we studied an lmna nonsense mutation encoding for the C-terminally truncated Lamin A/C (LMNA) variant Q517X, which was described in patients affected by a severe arrhythmogenic cardiomyopathy with history of sudden death. We found that LMNA

A bacteriophage tubulin harnesses dynamic instability to center DNA in infected cells. [PDF]
, 2014 Dynamic instability, polarity, and spatiotemporal organization are hallmarks of the microtubule cytoskeleton that allow formation of complex structures such as the eukaryotic spindle. No similar structure has been identified in prokaryotes.

Targeting the Achilles Heel of FtsZ: The Interdomain Cleft
Frontiers in Microbiology, 2021 Widespread antimicrobial resistance among bacterial pathogens is a serious threat to public health. Thus, identification of new targets and development of new antibacterial agents are urgently needed. Although cell division is a major driver of bacterial

Mitotic cell death induction by targeting the mitotic spindle with tubulin-inhibitory indole derivative molecules [PDF]
, 2017 Tubulin-targeting molecules are widely used cancer therapeutic agents. They inhibit microtubule-based structures, including the mitotic spindle, ultimately preventing cell division.

The discovery of tubulin [PDF]
The Journal of Cell Biology, 2005 In 1963, improved fixation methods led to the definitive identification of microtubules (see “Microtubules get a name” JCB. 168:852). Just one year later, Gary Borisy embarked on a daring project to isolate the main component of those microtubules.

Turgor Pressure and Possible Constriction Mechanisms in Bacterial Division
Frontiers in Microbiology, 2018 Bacterial cytokinesis begins with the assembly of FtsZ into a Z ring at the center of the cell. The Z-ring constriction in Gram-negative bacteria may occur in an environment where the periplasm and the cytoplasm are isoosmotic, but in Gram-positive ...

A permeabilized cell model for studying cell division: a comparison of anaphase chromosome movement and cleavage furrow constriction in lysed PtK1 cells. [PDF]
, 1981 After lysis in a Brij 58-polyethylene glycol medium, PtK1 cells are permeable to small molecules, such as erythrosin B, and to proteins, such as rhodamine-labeled FAB, myosin subfragment-1, and tubulin.

The Dam1 ring binds to the E-hook of tubulin and diffuses along the microtubule. [PDF]
, 2011 There has been much effort in recent years aimed at understanding the molecular mechanism by which the Dam1 kinetochore complex is able to couple microtubule depolymerization to poleward movement. Both a biased diffusion and a forced walk model have been
