Developing cell biology

open access: yeseLife, 2013
Experiments in Xenopus embryo extracts reveal that changes in cellular biochemistry cause mitotic spindles to decrease in size over the course of early development.

Regulation of Op18 during Spindle Assembly in Xenopus Egg Extracts [PDF]

open access: yes, 2001
Oncoprotein 18 (Op18) is a microtubule-destabilizing protein that is negatively regulated by phosphorylation. To evaluate the role of the three Op18 phosphorylation sites in Xenopus (Ser 16, 25, and 39), we added wild-type Op18, a nonphosphorylatable ...

Structural basis of tubulin recruitment and assembly by microtubule polymerases with tumor overexpressed gene (TOG) domain arrays

open access: yeseLife, 2018
XMAP215/Stu2/Alp14 proteins accelerate microtubule plus-end polymerization by recruiting tubulins via arrays of tumor overexpressed gene (TOG) domains, yet their mechanism remains unknown.

Microtubule Anchoring: Attaching Dynamic Polymers to Cellular Structures

open access: yesFrontiers in Cell and Developmental Biology, 2022
Microtubules are dynamic, filamentous polymers composed of α- and β-tubulin. Arrays of microtubules that have a specific polarity and distribution mediate essential processes such as intracellular transport and mitotic chromosome segregation. Microtubule

Modes of flagellar assembly in Chlamydomonas reinhardtii and Trypanosoma brucei

open access: yeseLife, 2014
Defects in flagella growth are related to a number of human diseases. Central to flagellar growth is the organization of microtubules that polymerize from basal bodies to form the axoneme, which consists of hundreds of proteins.

Dictyostelium Cell Fixation: Two Simple Tricks

open access: yesMethods and Protocols, 2020
We share two simple modifications to enhance the fixation and imaging of relatively small, motile, and rounded model cells. These include cell centrifugation and the addition of trace amounts of glutaraldehyde to existing fixation methods.

Altered chemomechanical coupling causes impaired motility of the kinesin-4 motors KIF27 and KIF7. [PDF]

open access: yes, 2018
Kinesin-4 motors play important roles in cell division, microtubule organization, and signaling. Understanding how motors perform their functions requires an understanding of their mechanochemical and motility properties.

Fractal, Scale Free Electromagnetic Resonance of a Single Brain Extracted Microtubule Nanowire, a Single Tubulin Protein and a Single Neuron

open access: yesFractal and Fractional, 2020
Biomaterials are primarily insulators. For nearly a century, electromagnetic resonance and antenna–receiver properties have been measured and extensively theoretically modeled.

Actin–microtubule coordination at growing microtubule ends [PDF]

open access: yesNature 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.

Peripheral nerve repair: a hot spot analysis on treatment methods from 2010 to 2014

open access: yesNeural Regeneration Research, 2015
Therapeutic strategies for neurological deficits and for promoting nerve regeneration after peripheral nerve injuries have received much focus in clinical research.
