The Polymers of Life: Exploring Cellular Function Through Polymer Concepts

Advanced Science, EarlyView.
Biomolecular phase separation reveals that a hidden layer of cellular organization is governed by the principles of polymer science. This review bridges polymer physics and cell biology, offering a primer on fundamental concepts, proposing a framework for interrogating cellular function, and synthesizing biophysical methods for decoding macromolecular ...

Cytoplasmic dynein nomenclature [PDF]

The Journal of Cell Biology, 2005
A variety of names has been used in the literature for the subunits of cytoplasmic dynein complexes. Thus, there is a strong need for a more definitive consensus statement on nomenclature. This is especially important for mammalian cytoplasmic dyneins, many subunits of which are encoded by multiple genes.

The roles of microtubule-based transport at presynaptic nerve terminals

Frontiers in Synaptic Neuroscience, 2016
Targeted intracellular movement of presynaptic proteins plays important roles during synapse formation and, later, in the homeostatic maintenance of mature synapses. Movement of these proteins is mediated by motor complexes travelling along intracellular

Axonemal Growth and Alignment During Paraspermatogenesis in the Marine Gastropod Strombus luhuanus

Frontiers in Cell and Developmental Biology, 2022
Parasperm are non-fertilizing sperm that are produced simultaneously with fertile eusperm. They occur in several animal species and show considerable morphological diversity.

Diverse Roles of Axonemal Dyneins in Drosophila Auditory Neuron Function and Mechanical Amplification in Hearing

, 2015
Much like vertebrate hair cells, the chordotonal sensory neurons that mediate hearing in Drosophila are motile and amplify the mechanical input of the ear.

PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana, many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Conserved Roles for the Dynein Intermediate Chain and Ndel1 in Assembly and Activation of Dynein

Nature Communications, 2023
Cytoplasmic dynein, the primary retrograde microtubule transport motor within cells, must be activated for processive motility through the regulated assembly of a dynein-dynactin-adapter (DDA) complex. The interaction between dynein and dynactin was initially ascribed to the N-terminus of the dynein intermediate chain (IC) and a ...

Functional State of the Axonemal Dyneins during Flagellar Bend Propagation

, 2002
When mouse spermatozoa swim in media of high viscosity, additional waves of bending are superimposed on the primary traveling wave. The additional (secondary) waves are relatively small in scale and high in frequency.

Making Two out of One: Kinesin Motors Driving Plant Cell Division

Cytoskeleton, EarlyView.
ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...
