Electronic Energy Migration in Microtubules [PDF]

arXiv, 2022
The repeating arrangement of tubulin dimers confers great mechanical strength to microtubules, which are used as scaffolds for intracellular macromolecular transport in cells and exploited in biohybrid devices. The crystalline order in a microtubule, with lattice constants short enough to allow energy transfer between amino acid chromophores, is ...

On subcellular distribution of the zinc finger 469 protein (ZNF469) and observed discrepancy in the localization of endogenous and overexpressed ZNF469

FEBS Open Bio, EarlyView.
ZNF469 regulates the expression of genes encoding extracellular matrix proteins. Endogenous ZNF469 is predominantly cytoplasmic, while in transfected cells, it forms aggregates reminiscent of biomolecular condensates, located mainly in the nucleus. These condensates exhibit overlapping staining with proteasomes and are also associated with the mitotic ...

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.

Tubulin dipole moment, dielectric constant and quantum behavior: computer simulations, experimental results and suggestions [PDF]

BioSystems, 77:73-85 (2004), 2004
We used computer simulation to calculate the electric dipole moments of the alpha and beta tubulin monomers and dimer and found those to be |palpha|=552D, |pbeta|=1193D and |palpha-beta|=1740D respectively. Independent surface plasmon resonance (SPR) and refractometry measurements of the high-frequency dielectric constant and polarizability strongly ...

Structure and Dynamics of Single-isoform Recombinant Neuronal Human Tubulin*♦

Journal of Biological Chemistry, 2016
Microtubules are polymers that cycle stochastically between polymerization and depolymerization, i.e. they exhibit “dynamic instability.” This behavior is crucial for cell division, motility, and differentiation.

Histone Deacetylase 6 Brain PET in Amyotrophic Lateral Sclerosis‐Frontotemporal Spectrum Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective [18F]EKZ‐001 is a positron emission tomography (PET) tracer targeting histone deacetylase 6 (HDAC6), an enzyme responsible for intracellular transport and clearance of misfolded proteins. HDAC6 modulation is a promising treatment strategy in neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS).

Rbl2p, a yeast protein that binds to β-tubulin and participates in microtubule function in vivo [PDF]

, 1995
Genetic configurations resulting in high ratios of β-tubulin to α-tubulin are toxic in S. cerevisiae, causing microtubule disassembly and cell death. We identified three non-tubulin yeast genes that, when overexpressed, rescue cells from excess β-tubulin.

α-Synuclein regulates the partitioning between tubulin dimers and microtubules at neuronal growth cone

Communicative & Integrative Biology, 2017
The partitioning between tubulin dimers and microtubules is fundamental for the regulation of several neuronal activities, from neuronal polarization and processes extension to growth cone remodelling.

The structured core of human β tubulin confers isotype-specific polymerization properties

Journal of Cell Biology, 2016
The tubulin gene family encodes multiple tubulin isotypes that can have distinct polymerization properties. Pamula et al. show that residue changes within β tubulin’s structured core are largely responsible for isotype-specific differences in dynamic ...

Colchicine Concentrations and Relationship With Colchicine Efficacy and Adverse Events: Post Hoc Analysis of a Randomized Clinical Trial of Colchicine for Gout Flare Prophylaxis

Arthritis Care &Research, EarlyView.
Objective Our objective was to examine the relationship between colchicine plasma concentrations and clinical and demographic factors and to determine the relationship between colchicine concentrations and colchicine efficacy and colchicine‐specific adverse events.
