Presynaptic Precursor Vesicles—Cargo, Biogenesis, and Kinesin-Based Transport across Species
Cells, 2023 The faithful formation and, consequently, function of a synapse requires continuous and tightly controlled delivery of synaptic material. At the presynapse, a variety of proteins with unequal molecular properties are indispensable to compose and control ...

Mechanisms of Polarized Organelle Distribution in Neurons
Frontiers in Cellular Neuroscience, 2016 Neurons are highly polarized cells exhibiting axonal and somatodendritic domains with distinct complements of cytoplasmic organelles. Although some organelles are widely distributed throughout the neuronal cytoplasm, others are segregated to either the ...

Kinesin-5 inhibitor resistance is driven by kinesin-12 [PDF]
Journal of Cell Biology, 2016 The microtubule (MT) cytoskeleton bipolarizes at the onset of mitosis to form the spindle. In animal cells, the kinesin-5 Eg5 primarily drives this reorganization by actively sliding MTs apart. Its primacy during spindle assembly renders Eg5 essential for mitotic progression, demonstrated by the lethal effects of kinesin-5/Eg5 inhibitors (K5Is ...

The developmental biology of kinesins
Developmental Biology, 2021 Kinesins are microtubule-based motor proteins that are well known for their key roles in cell biological processes ranging from cell division, to intracellular transport of mRNAs, proteins, vesicles, and organelles, and microtubule disassembly. Interestingly, many of the ~45 distinct kinesin genes in vertebrate genomes have also been associated with ...

On the Origin of Kinesin Limping [PDF]
Biophysical Journal, 2009 Kinesin is a dimeric motor with twin catalytic heads joined to a common stalk. Kinesin molecules move processively along microtubules in a hand-over-hand walk, with the two heads advancing alternately. Recombinant kinesin constructs with short stalks have been found to "limp", i.e., exhibit alternation in the dwell times of successive steps.

eLife, 2020 Intracellular transport relies on multiple kinesins, but it is poorly understood which kinesins are present on particular cargos, what their contributions are and whether they act simultaneously on the same cargo.

A look into kinesin's powerhouse [PDF]
FEBS Letters, 2001 Kinesins are microtubule‐dependent motors that serve a multitude of cellular purposes. The conserved motor domain provides the energy required for these processes. Shortly after the solution of the first kinesin motor domain crystal structures the similarity to myosin and G‐proteins was noted.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics
FEBS Letters, EarlyView.Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

, 2015 Human cells express 45 kinesins, microtubule motors that transport a variety of molecules and organelles within the cell. Many kinesins also modulate the tracks they move on by either bundling or sliding or regulating the dynamic assembly and disassembly
