Modeling the Effects of Drug Binding on the Dynamic Instability of Microtubules
, 2011 We propose a stochastic model that accounts for the growth, catastrophe and rescue processes of steady state microtubules assembled from MAP-free tubulin.

The Journal of Cell Biology, 2002 ![Graphic][1] Conoids consist of tubulin in an unconventional arrangement.The pathogens that cause malaria, cryptosporidiosis, and toxoplasmosis share a baffling common feature: a cone-shaped apical structure called the conoid.

Molecular Oncology, EarlyView.RKIP, a metastasis suppressor protein, modulates key oncogenic pathways in lung adenocarcinoma. In silico analyses linked low RKIP expression to poor survival. Functional studies revealed RKIP overexpression reduces tumor aggressiveness and enhances sensitivity to EGFR‐targeted therapies, while its loss promotes resistance.

Ophiostoma gemellus and Sporothrix variecibatus from mites infesting Protea infructescences in South Africa [PDF]
, 2008 Ophiostoma (Ophiostomatales) represents a large genus of fungi mainly known from associations with bark beetles (Curculionidae: Scolytinae) infesting conifers in the northern hemisphere.

Molecular Oncology, EarlyView.Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Interaction of diazonamide A with tubulin
Archives of Biochemistry and Biophysics, 2020 [3H]Diazonamide A ([3H]DZA), prepared from the natural product isolated from Diazona angulata, bound to tubulin in larger aberrant assembly products (>500 kDa by sizing HPLC) but not to the αβ-tubulin heterodimer. The binding reaction was rapid, but stoichiometry was low.

The binding of Isocolchicine to Tubulin [PDF]
Journal of Biological Chemistry, 1989 Isocolchicine is a structurally related isomer of colchicine altered in the methoxytropone C ring. In spite of virtual structural homology of colchicine and isocolchicine, isocolchicine is commonly believed to be inactive in binding to tubulin and inhibiting microtubule assembly.

Survivin and Aurora Kinase A control cell fate decisions during mitosis
Molecular Oncology, EarlyView.Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.

Much More Than a Scaffold: Cytoskeletal Proteins in Neurological Disorders
Cells, 2020 Recent observations related to the structure of the cytoskeleton in neurons and novel cytoskeletal abnormalities involved in the pathophysiology of some neurological diseases are changing our view on the function of the cytoskeletal proteins in the ...

The mechanism of anaphase spindle elongation: uncoupling of tubulin incorporation and microtubule sliding during in vitro spindle reactivation. [PDF]
, 1988 To study tubulin polymerization and microtubule sliding during spindle elongation in vitro, we developed a method of uncoupling the two processes. When isolated diatom spindles were incubated with biotinylated tubulin (biot-tb) without ATP, biot-tb was ...
