Chlamydia Hijacks ARF GTPases To Coordinate Microtubule Posttranslational Modifications and Golgi Complex Positioning. [PDF]
The intracellular bacterium Chlamydia trachomatis develops in a parasitic compartment called the inclusion. Posttranslationally modified microtubules encase the inclusion, controlling the positioning of Golgi complex fragments around the inclusion.

Microtubules acquire resistance from mechanical breakage through intralumenal acetylation
Acetylation keeps microtubules strong Cells need microtubules for intracellular transport and to avoid being crushed. On investigating microtubule breakage in live fibroblasts, Xu et al.

Formins have recently been recognized as prominent regulators of the microtubule (MT) cytoskeleton where they modulate the dynamics of selected MTs in interphase and mitosis. The association of formins with the MT cytoskeleton and their action on MT dynamics are relatively unexplored areas, yet growing evidence supports a direct role in their ...

The Mating-specific Gα Interacts with a Kinesin-14 and Regulates Pheromone-induced Nuclear Migration in Budding Yeast [PDF]
As a budding yeast cell elongates toward its mating partner, cytoplasmic microtubules connect the nucleus to the cell cortex at the growth tip.

Flexural rigidity of microtubules and actin filaments measured from thermal fluctuations in shape
Microtubules are long, proteinaceous filaments that perform structural functions in eukaryotic cells by defining cellular shape and serving as tracks for intracellular motor proteins.

A "MICROTUBULE" IN A BACTERIUM [PDF]
A study of the anchorage of the flagella in swarmers of Proteus mirabilis led to the incidental observation of microtubules. These microtubules were found in thin sections and in whole mount preparations of cells from which most of the content had been released by osmotic shock before staining negatively with potassium phosphotungstate (PTA).

Microtubules Gate Tau Condensation to Spatially Regulate Microtubule Functions
Tau is an abundant microtubule-associated protein in neurons. Tau aggregation into insoluble fibrils is a hallmark of Alzheimer’s disease and other types of dementia1, yet the physiological state of tau molecules within cells remains unclear.

Kinetically distinct phases of tau on microtubules regulate kinesin motors and severing enzymes
Tau is an intrinsically disordered protein, which diffuses on microtubules1. In neurodegenerative diseases, collectively termed tauopathies, malfunction of tau and its detachment from axonal microtubules are correlated with axonal degeneration2.

The Minisymposium “The Life of a Microtubule: Birth, Dynamics and Function†highlighted new findings on how microtubules (MTs) are made, how their length and spatial organization is regulated, and finally how they contribute to cellular functions.

Diffusion of myosin V on microtubules [PDF]
Organelle transport in eukaryotes employs both microtubule and actin tracks to deliver cargo effectively to their destinations, but the question of how the two systems cooperate is still largely unanswered.
