Ectopic A-lattice seams destabilize microtubules [PDF]

, 2014
Natural microtubules typically include one A-lattice seam within an otherwise helically symmetric B-lattice tube. It is currently unclear how A-lattice seams influence microtubule dynamic instability.

Isolation of Microtubules and Microtubule Proteins

Current Protocols in Cell Biology, 2008
AbstractThis unit describes various protocols for the isolation and purification of the main constituents of microtubules, chiefly α‐ and β‐tubulin, and the most significant microtubule associated proteins (MAPs), specifically MAP1A, MAP1B, MAP2, and tau.

Vibrations in Microtubules [PDF]

Journal of Biological Physics, 1997
Vibrations in microtubules and actin filaments are analysed using amethod similar to that employed for description of lattice vibrationsin solid state physics. The derived dispersion relations show thatvibrations in microtubules can have optical and acoustical branches.The highest frequency of vibrations in microtubules and in actinfilaments is of the ...

Actin–microtubule coordination at growing microtubule ends [PDF]

Nature Communications, 2014
To power dynamic processes in cells, the actin and microtubule cytoskeletons organize into complex structures. Although it is known that cytoskeletal coordination is vital for cell function, the mechanisms by which cross-linking proteins coordinate actin and microtubule activities remain poorly understood.

Segregation of a microsporidian parasite during host cell mitosis [PDF]

, 1999
We investigated the segregation of an intracellular microsporidian parasite during host cell division. A time-course experiment was carried out to examine the distribution of parasites relative to host chromosomal DNA via light and electron microscopy.

Microtubules in cell migration

Essays in Biochemistry, 2019
Directed cell migration is critical for embryogenesis and organ development, wound healing and the immune response. Microtubules are dynamic polymers that control directional migration through a number of coordinated processes: microtubules are the ...

Microtubule severing [PDF]

Cell Motility and the Cytoskeleton, 1999
The regulation of microtubule stability by severing of the polymer along its length is a newly appreciated and potentially important mechanism for controlling microtubule function. Microtubule severing occurs in living cells, but direct observation of this event is infrequent.

Mammalian kinetochores count attached microtubules in a sensitive and switch-like manner. [PDF]

, 2019
The spindle assembly checkpoint (SAC) prevents anaphase until all kinetochores attach to the spindle. Each mammalian kinetochore binds many microtubules, but how many attached microtubules are required to turn off the checkpoint, and how the kinetochore ...

Microtubules, microtubule-interfering agents and apoptosis

Apoptosis, 2003
Microtubules are dynamic polymers that play crucial roles in a large number of cellular functions. Their pivotal role in mitosis makes them a target for the development of anticancer drugs. Microtubule-damaging agents suppress microtubule dynamics, leading to disruption of the mitotic spindle in dividing cells, cell cycle arrest at M phase, and late ...

Tubulin acetylation protects long-lived microtubules against mechanical aging

Nature Cell Biology, 2017
Long-lived microtubules endow the eukaryotic cell with long-range transport abilities. While long-lived microtubules are acetylated on Lys40 of α-tubulin (αK40), acetylation takes place after stabilization and does not protect against depolymerization ...
