Template-free 13-protofilament microtubule–MAP assembly visualized at 8 A resolution [PDF]

open access: yes, 2010
Microtubule-associated proteins (MAPs) are essential for regulating and organizing cellular microtubules (MTs). However, our mechanistic understanding of MAP function is limited by a lack of detailed structural information. Using cryo-electron microscopy

Redox imbalance induced by docetaxel in the neuroblastoma SH-SY5Y cells: a study of docetaxel-induced neuronal damage

open access: yesRedox Report, 2021
Objectives In cancer survivors, chemotherapy-associated adverse neurological effects are described as side effects in non-targeted tissue. We investigated the role of redox-imbalance in neuronal damage by a relative low dose of Docetaxel (DTX).

Microtubules in Microorganisms: How Tubulin Isotypes Contribute to Diverse Cytoskeletal Functions

open access: yesFrontiers in Cell and Developmental Biology, 2022
The cellular functions of the microtubule (MT) cytoskeleton range from relatively simple to amazingly complex. Assembled from tubulin, a heterodimeric protein with α- and β-tubulin subunits, microtubules are long, hollow cylindrical filaments with ...

Polymorphism in tubulin assemblies: a mechanical model [PDF]

open access: yesarXiv, 2022
We investigate the mechanical origin of polymorphic structures in two-dimensional tubulin assemblies, of which microtubules are the best known example. These structures feature twisted ribbons, flat tubulin sheets, macrotubules, and hoops, and they spontaneously assemble depending on the chemical environment.

Simulations of tubulin sheet polymers as possible structural intermediates in microtubule assembly [PDF]

open access: yesPLoS ONE, 2009, 4(10): e7291., 2009
The microtubule assembly process has been extensively studied, but the underlying molecular mechanism remains poorly understood. The structure of an artificially generated sheet polymer that alternates two types of lateral contacts and that directly converts into microtubules, has been proposed to correspond to the intermediate sheet structure observed

Molecular basis for resistance of acanthamoeba tubulins to all major classes of antitubulin compounds [PDF]

open access: yes, 2007
Tubulin is essential to eukaryotic cells and is targeted by several antineoplastics, herbicides, and antimicrobials. We demonstrate that Acanthamoeba spp.

The discovery of tubulin [PDF]

open access: yesThe 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.

Resolving controversy of unusually high refractive index of tubulin [PDF]

open access: yes, 2016
Refractive index of tubulin is an important parameter underlying fundamental electromagnetic and biophysical properties of microtubules - protein fibers essential for several cell functions including cell division. Yet, the only experimental data available in the current literature show values of tubulin refractive index (n\,=\,2.36\,-\,2.90) which are

Tubulin Inhibitor-Based Antibody-Drug Conjugates for Cancer Therapy

open access: yesMolecules, 2017
Antibody-drug conjugates (ADCs) are a class of highly potent biopharmaceutical drugs generated by conjugating cytotoxic drugs with specific monoclonal antibodies through appropriate linkers.

Loss of tubulin deglutamylase CCP1 causes infantile‐onset neurodegeneration

open access: yesEMBO Journal, 2018
A set of glutamylases and deglutamylases controls levels of tubulin polyglutamylation, a prominent post‐translational modification of neuronal microtubules.
